Based on the concept of sustainable development, environmental logistics achieves the aim of environmental protection and make the best of recourses by applying advanced technology and improve each link of traditional logistics, especially distribution. Environmental logistics distribution has many different modes, many factors should be considered to achieve distribution optimization. Finally the research puts forward advice for the development of environmental logistics distribution in the future. Keywords –environmental logistics, distribution, distribution optimization, distribution system, suggestions In order to achieve some benefits, traditional logistics enterprise operators only pay attention to the efficiency of goods flow, however, it often ignores the protection of the environment. Materials bring negative effects to the traffic and environment in the process of circulation. Modern logistics is no longer at the expense of the environment, should advocate of environmental and sustainable development of the logistics concept. In the twenty-first Century, environmental logistics is the direction and trend of logistics development. Environmental logistics is a new logistics management mode including forward logistics and reverse logistics. Recycling and reproduction consumer products realize the goods recycling and secondary utilization, thus the reverse logistics emerged. Reverse logistics rational uses existing resources by the resources integration again, and achieve the purpose of reducing pollution to the environment. Make use of advanced logistics transportation equipment and management technology, planning and implementation of transportation, distribution and logistics activities, environmental logistics realizes logistics transportation links in harmony with the natural environment development, really achieving sustainable development[1-2]. I Content and Characteristics of Environmental Logistics A The Content of Environmental Logistics Environmental logistics refers to inhibiting harm to the environment during the process of logistics and realizes the purification of the logistics environment and makes the best use of logistics resources at the same time. Figure 1 shows the relationship among economy, logistics, life and environment[3]. In the figure, Ec presents economy; Lo presents logistics; Li presents life; En presents environment. B The Characteristics of Environmental Logistics First, symbiotic relationship between environmental logistics and ecological environment protects the environment and pulls of sustainable development of social economy environment. Second, economization. In our life, excessive raw materials are unnecessary waste, products are stored in the warehouse because supply exceeds demand, which eventually lead the products obsolescence and loses the Past Present Ec Ec Lo Li Future Ec Lo Lo En Li En Li En Fig. 1.Relationship among logistics, economy, life and environment Environmental supply logistics Environmental production logistics Forward logistics Reverse logistics Environmental marketing logistics Fig. 2. Constitutional diagram of environmental logistics original product value. In the field of production, consumption and distribution of all kinds of waste phenomenon exist everywhere. Third, circulation. The product recovery is a very important link to secondary utilization of waste materials. The renewable resources recycling, such as raw materials regeneration, recycling of waste materials and so on, is all that environmental logistics should consider. It is such a need that forms reverse logistics[4]. Figure 2 shows that environmental logistics contributes to logistics and reverse logistics. C Rationale about Environmental Logistics a. Sustainable Development of Environmental Theory From the view point of environmental protection, a very good coordination among the economy, society and environment is needed to form a logistics system symbiosis with the environment, reduce or even eliminate the harm to the environment. b. Ecological Ethics From an ethical perspective, people should establish a friendly relationship, not regard the nature as an object for exploitation, protect nature, love nature, and pursue the whole balance between mankind and natural. Ecological ethics theory’s ultimate goal is to pursue the maximum benefits of the whole, reducing natural exploitation and interference between human and nature, to realize harmonious development. c. The Theory of Ecological Economics. Economic interest means the maximization of benefit. But ecological economists pursue the economic benefit, social benefit, environmental benefit, ecological environment and economy to coordinate develop. The theory of ecological economics mainly studies the relationship between ecological system and economic system. How to better realize the ecological system and the economic system coordinated development is the main goal of ecological economists[5,6]. II Structural System Research about Environmental Logistics Distribution A The Content of Environmental Logistics Distribution Environmental logistics, in our national standards “logistics terms” is defined as inhibition to causing harm to the environment in the process of the logistics, realizing the purification of the logistics environment and making the best use of logistics information[7] at the same time. The distribution is, defined as according to user requirements, chose, process, pack, classify, match and send articles to the designated locations of logistics activities on time as economically and rationally as possible[8]. Environmental logistics distribution is mainly composed of environmental transportation, environmental packaging, environmental handling and transporting, environmental stock and environmental distribution processing subsystems. But in the subsystems there exist serious environmental problems, it is necessary to formulate environmental policy and planning, perfect laws and regulations, and for staff to receive environmental education. B Research on the Mode of Environmental Distribution a. Reverse Logistics Reverse logistics perfects traditional forward logistics based on the logistics mode of circular economy. Circular environmental logistics mode is “environmental raw materials acquisition, environmental production, environmental consumption, environmental recycling and environmental reproduction”. This process includes raw materials by-product recycling, green packaging recycling, waste recycling, garbage collection and recycle. Reverse logistics recycles value and surplus value commodity to reduce waste. On the other hand, it saves raw materials also brings certain economic benefit by the product updating, assembling recycling products into new products. Development of new technology makes the products’ secondary utilization available. b. Joint Distribution Joint distribution is a partnership between distribution companies and distribution companies, or between distribution center and distribution center, to obtain the intensive operation mode. Joint distribution can avoid the enterprise waste transport vehicle and resources, because of a small portion of the user’s needs, more and more companies send goods just in time, even the car is not fully loaded. To take full advantage of enterprise resources is necessary. Originally many enterprises operate independently to complete their respective distribution tasks by a lot of cars, but now they only need a car, or a small amount of vehicles. Thus, it saves vehicle resources, on the other hand, decreases traffic pressure and traffic congestion. c. Third-Party Logistics (3PL) Enterprises outsource logistics business to professional logistics companies but mainly focus on the development of enterprise’s own products and their function and characteristics, so that the products on the market are more competitive. Third-party logistics is neither logistics supplier nor logistics buyer but provides professional logistics services, logistics operation and management. Third-party logistics refers to external service providers that provide some or all of the logistics function. It is a form of logistics professionalization. The services of third-party logistics includes logistics system design, storage, information management, consultation, stock of goods and agents[9-11]. C Factors of Environmental Logistics Distribution Solution Distribution is one of the most important parts in the process of logistics. To achieve environmental logistics distribution, some factors should be considered, it takes advantage of enterprises and traffic, even environment. a. Shortest Shipping Distance Shipping distance is in proportional to the distribution cost, namely, the longer the shipping distance, the higher the transport cost. b. Fastest Shipping Speed One of the main factors customer evaluate distribution service level is punctual whether it is or not. c. Lowest Shipping Cost The biggest benefit for enterprise is a common object for business. The enterprise reduces the cost equally to increase the effectiveness for the enterprise. d. Least Shipping Consumption Distribution involves vehicles, personnel, fuel and equipment. Rational allocation of vehicles can decrease vehicles and drivers to save labor. Fuel consumption and equipment saving, in the process of transporting should be taken into account. The essence is a multi-objective optimization problem, we generally regard multiple target simply as single objective problem[12]. III Measures and Suggestions about Establishing Environmental Logistics Distribution System A Strengthen Environmental Logistics Infrastructure Construction Infrastructure is the foundation and safeguard for logistics normal operation. Perfect function, reasonable layout logistics infrastructure is conducive to promoting the construction of environmental logistics system and contributes to the healthy and fast development of environmental logistics. Environmental logistics infrastructure development is progressive, systemic and resource integrated characteristics. Environmental logistics infrastructure construction is divided into three stages: to construct demonstration project, to promote environmental logistics infrastructure system construction, and to improve environmental logistics infrastructure system. Then, plan and coordinate environmental logistics infrastructure. Whether to integrate the existing facilities and comprehensive utilization, or plan and coordinate the newly-built facilities, or accomplish facilities the reasonable layout and perfect function according to the development view of comprehensive, coordinated, sustainable development advance[13].

B Construction of the Environmental Logistics Transportation System In addition to good use of existing three kinds of transportation modes, we need to positively innovate new transport mode. Transportation cost is an important part of logistics cost, a successful logistics distribution system can not be separated with high efficiency, quick response ability, low transportation cost transportation network. Transport network design is a strategic decision, decision makers need to be aware of goods flow, network connection and node structure of the whole supply chain. So optimizing transportation route is also very important[14]. C Institutional Innovation First, it is incentive mechanism including green subsidy policies, preferential tax policy and government procurement policy and so on. In order to promote the development of environmental logistics, the government must establish effective environmental incentive policy. This kind of incentive policy is mainly through economic levers to inspire and guide the behavior of main logistics companies[15]. And then the government system should include environmental institution and charging institution. Government system can make up for the lack of incentive mechanism binding. The advantage of government system is definite goal, the mandatory implementation and direct effect. [9] Y.H. Ru, B.H.
