Synthetic Evaluation of the Landscape Ecological Security around Taihu Lake

QIU Heng-jia et al(Suzhou Polytechnical Institute of Agriculture,Suzhou,Jiangsu 215008)  
In this paper,an evaluation indicator system of landscape ecological security around Taihu Lake was put forward,including 25 evaluation indicators of landscape structure,landscape function and landscape threatening.Wuzhong district of Suzhou city being taken as an example,with this indicator system,the comprehensive evaluation of landscape ecological security in 1984 and 2002 was conducted.The result showed that the synthetic evaluation indicators of terrestrial landscape ecological security were decreased from 63.29% in 1984 to 60.44% in 2002.However,the landscape ecological security in Wuzhong was in a good state because of the society-economy benefit of landscape increasing greatly.From 1984 to 2002,the safety levels of landscape structure and landscape threatening were decreased rapidly by 16.95% and 19.20%,respectively.So there was a lot of unsafe hidden trouble about landscape structure,landscape threatening and landscape ecological quality.It was believed that the scientific and reasonable measures should be further strengthened,so as to increase the safety level of landscape ecosystem around Taihu Lake.
