Ma Shi Chau??



A rectangular shaped island about 1.5km long ,
500m wide and 61 hectares.
Connected to Yim Tin Chau
by a sand bar.
Northeasterly direction
Research Statement
Ma Shi Chau Special Area comprises 4 islands in Tolo
Harbour, namely, Ma Shi Chau, A Chau, Yeung Chau
and unnamed island. Along the Tolo Channel, it is long
and narrow in shape due to the presence of fault line.
In April 1999, Ma Shi Chau and its three adjacent
islands were designated as a Special Site of Scientific
Interest (SSSI) under the management of the Country
and Marine Parks Authority of the Agriculture,
Fisheries and Conservation Department. It is valuable
to classify Ma Shi Chau as a SSSI because there
contain many geological treasures.
Tasks
1. Students are divided into 3 or 4 groups.
2. You have to collect supportive evidence
along the Ma Shi Chau natural path to prove
why it is classified as the site of SSSI.
3. Each group has to introduce the geological
features or special landforms of any 2 specific
points that you have chosen along the natural
path.

Problem statement

合和計劃在船街及堅尼地道中約十二萬三千
九百四十呎地皮，興建兩幢六十層高的4星
級酒店大樓，提供2,280個房間及會議展覽
中心等設施。該酒店樓面面積約一百零五萬
四千七百餘方呎，其餘四十四萬七千餘方呎
為酒店附屬設施，而該項目提供一百一十九
萬餘方呎的休憩設施。
合和發展這項計劃大大提升休憩場地的面積，
而這些休憩場地亦會提供所有公眾人士使用。
而合和更主動提出把船街古老大宅「南固台」
保存翻新，以保留該具歷史價值之建築物，周
邊地皮亦會作休憩地，有助美化周邊鄰里環境。
另一方面，此項計劃亦不會對堅尼地道及鄰近
交通造成影響，這是由於堅尼地道總流量並未
達到飽和。
在發展過程中，砍伐樹木是無可避免的，雖然
該發展項目將砍伐337棵樹，但均非珍貴樹木，
由於多年沒有保養及護理，所以價值不高。合
和將會於休憩地方種植310棵樹，新種樹木將
受到特別護理，肯定較現有野生為佳。酒店大
樓雖樓高60層，但最高點亦遠低於山脊線，不
會阻礙附近景觀。
