Chapter1 Character of physical geography • 1、Synthesis : Physical geography is a intersecting subject and has relation with many subjects. • 2 、 Regionality: Regional character, regional relation, and regional differentiation are main realm of Physical geography. • 3 、 Environmentality: Environment of the Earth’s surface system, which human being depended on, is the research object of physical geography. • 4 、 Systematically: The environment of earth’s surface, which called as the earth’s surface system,has globality, gradation, variability, functionality. Chapter1 Definition of physical geography Physical geography is mainly about composition, structure, regional differentiation, development of the natural environment of earth’s surface system. By systematical, synthetical, regional viewpoints and methods, we can evaluate, predict, plan, manage, optimize, regulate and control the Earth’s surface system. Chapter1 Physical geography and the earth’s surface system The earth is a huge system. The earth system can be divided into the earth’s surface system and Subterrestrial system. The earth’s surface system can be divided into natural system and human system. Physical geography is mainly on the Earth’s natural surface system. human system Extraterrestrial system (Astronomy) The earth’s surface system (Geography ) (Humanic geography) Natural system (Physical geography) The earth system (Geoscience) Subterrestrial system ( Geology) Chapter1 Relation between physical geography and other subjects The Earth’s surface system consists of atmosphere, hydrosphere, lithosphere and biosphere. The relevant subjects are meteorology, hydrology, geology and biology. Physical geography covers the four subjects and synthesizes them to an entity. So it can be said that physical geography is an intersecting subject on met eo rolo gy, hy dro logy, geology and biology Meteorology Geology Physical geography Hydrology Biology Relation between physical geography and other subjects Chapter 2 The earth and the Earth’s Surface Environment • Section 1 The earth in universe • Section 2 Impact of extraterrestrial system on the Earth’s surface environment • Section 3 Impact of subterrestrial system on the Earth’s surface environment Chapter 2 The Earth in universe 1、The distance from the sun to the earth and the environment significance : The distance is neither too short nor too long, creating suitable condition for life origin. 2、 The mass of the earth and its environmental effect : The mass of the earth is neither too big nor too small, so the gravitation on it is moderate, atmosphere and hydrosphere could be formed, providing suitable condition for origin of life. 3、The shape of the Earth and its geographic significance: The shape of the Earth result in zonal distribution of solar energy and relevant factors (such as climate, soil, vegetation etc.) on the Earth’s surface. Chapter 2 The earth in universe 4、 movements of the earth and their environmental significance : 1) Rotation of the earth and its geographic significance Rotation of the earth results in subrogation of day and night; Rotation of the Earth results in local hour; Rotation of Earth results in Deflection force on the earth. 2) Revolution of the earth and its geographic significance Revolution of the earth results in change of seasons; Revolution of the earth results in change of day and night length; Revolution of the earth has great significance for adjusting the Earth’s surface temperature and origin of life. Chapter 2 Impact of extraterrestrial system on the earth’s surface environment 1、Source of energy The energy that maintains development of the earth’s surface system mainly comes from solar radiation. As a result of zonal difference of solar radiation that earth’s surface accepted, planetary wind belt, monsoon, water circulation, ocean current and weathering were formed. 2、 Effect of gravitation The sun’s and other planets ’ gravitation leads the earth moving along steady orbit, period and velocity. As a result of the Sun’s and the Moon’s gravity, the tide was formed on the Earth. Chapter 2 Impact of extraterrestrial system on the earth’s surface environment 3、 Environmental effect of meteorite Meteorite can conduce earthquake Meteorite can change landforms of the earth’s surface, produce Meteorite pit and ring mountain. Meteorite can lead hazards to the earth’s surface environment. Meteorite can also lead lithosphere breaking, induce the Plate breaking and moving. 4、Impact of other universe factors There is material exchange between the earth’s surface system and extraterrestrial system . The solar activity . The solar wind. Chapter 2 Impact of subterrestrial system on the earth’s surface system 1、Source of the energy Solar radiation is the main energy source of the earth’s surface system, but subterrestrial system also impacts the earth’s surface system. 2、 Material exchange There exists continuous material exchange between subterrestrial system and the earth’s surface system. 3、The other environment effects of subterrestrial activity Subterrestrial activity also has other impacts on the earth’s surface system. volcano, earthquake; movement and transformation of Centrosphere and Mantle material are examples. Chapter 3 The Earth’s Surface Environment and the Earth’s surface system • Section 1 Components of the earth’s surface system • Section 2 Structure of the earth’s surface system • Section 3 Functions of the earth’s surface system • Section 4 The earth’s surface environment and the Man Chapter 3 Four spheres of the Earth’s surface system The Earth can be divided into interior spheres and exterior spheres. the interior spheres include the earth ’s crust(A), mantle(B), centrosphere(C). B C A The exterior spheres include lithosphere, atmosphere, hydrosphere and biosphere. Lithosphere is composed of solid rocks in earth’s surface system; Atmosphere is composed of gases that surround the earth; Hydrosphere is composed of all forms of water in earth’s surface system ; Biosphere is composed of all living organism in the earth’s surface system. Chapter 3 Human being in the Earth’s surface system Human being is a part of biosphere, but human being has essential disparity with other living things. Relations between Human being and the Earth’s surface system can be described as follow: (1) Human being is a part of the biosphere, but it is different from other living things. (2) Human live in the common boundary face of four spheres. The four spheres of the Earth’s surface system provide suitable environment for human origin. (3) Human have great impacts on four spheres of the Earth’s surface system . Human and four spheres act on one another, forming the earth’s surface system . Chapter 3 Atmospheric Biosphere Man Hydrosphere Lithosphere Chapter 3 Three kingdoms Physical environment usually be divided into inorganic kingdom and organic kingdom, however, that theory seems cannot explain the Earth’s surface system perfectly, for it cannot well illustrate human being’s action on environment and relations between human and nature, it is necessary to emphasize human being’s function, so human kingdom was put forward, we can say that the earth’s surface system is composed of inorganic kingdom , organic kingdom and human kingdom, three kingdoms acted on one another. Chapter 3 Inorganic kingdom Organic kingdom Human kingdom Chapter 3 Structure of the earth’s surface system 1 、Vertical sphere: Vertical spheres of the Earth system are very clear: from centrosphere, mantle, the earth's crust to hydrosphere, atmosphere etc. Atmosphere also can be divided into troposphere, stratosphere, mesosphere, thermosphere and exosphere. 2 、 Horizontal differentiation: It is horizontal difference of physical environment. 3、The stereo intersectional structure : Lithosphere, hydrosphere, atmosphere, biosphere consist the earth’s surface environment, they are not absolutely separate, but interact on one another, forming a stereo intersectional structure. 4、The multilevel nesting: Different scale environment systems are intercrossed and overlapped, they interact on one another. Chapter 3 Function of the earth’s surface system 1、Material transmission, energy flow, information transfer In general, a system has functions of material transmission, energy flow, information transfer. Vertical direction, There exist material transmission, energy flow, information transfer among various spheres and sub-spheres. Horizontals direction, There exist material transmission, energy flow, information transfer among oceans , continents and regions. There exist material transmission, energy flow, information transfer among biosphere and other spheres Chapter 3 functions of the earth’s surface system 2. Predictable and adjustable system Changes of the earth’s surface system can be predicted by material transmission, energy flow and information transfer. In order to optimize regulate and control earth’s surface system, We can alter the structure and the development trend of the system by interfering its material transmission, energy flow and information transfer.
