Analysis on Dynamic Change Process of the Ecological Environment Quality of 13 a of Wuzhong District in Suzhou City and Its Countermeasures
摘要
Abstract
The article quantitatively analyzes the dynamic change of ecological environment quality in Wuzhong district of Suzhou city from 2000 to 2013 to provide countermeasures for the protection and improvement of ecological environment quality in this area.It obtained by simulation the NPP dynamic change of the area based on CASA model and remote sensing and according to meteorological data of Wuzhong district of Suzhou city from 2000 to 2013 and obtained dynamic change of land cover in this area with the method of supervised classification.It also analyzed the cause of ecological environment dynamic change according to climate change law.The result shows that,the net primary productivity reduced 0.8 Gg;the land cover of overall 406.41 km2 changed,accounting for 18.15％ of total land cover area in Wuzhong city from 2000 to 2013;the thickness of vegetation,ecological carrying capacity and carbon sequestration amount decreased at an annual declining speed of 1.09％.The fast urbanization process in Wuzhong district of Suzhou city caused a large amount of high NPP covered land changed into low NPP one and the ecological environment tend to degrade.关键词
