Analysis of the Landscape Ecology in Chongqing Area

——With Shiban Town, Jinfu Town, Dongsun Town, Taojia Town, and Xipeng Town as the cases

Abstract：

This paper used analysis of landscape ecology pattern, and obtained the basic shape data such as the girths and acreages of various landscapes of several towns from the actuality of these towns in Chongqing combined with multiple references. Through calculation of these data, the author obtained many landscape patter indexes such as the interior-to-edge ratios、the fractal dimensions, the diversity indexes, the dominance indexes, the separation indexes, the coefficients of variation etc. The landscape pattern change of these towns from 1999 to 2004 was also compared. The final results showed that most of the plant-covering landscapes in the research plots are reducing, and the edge lengths of the landscapes in each research plots exhibited declining trend from 1999 to 2004, so do the patch densities. The results suggested that the landscape fragmentation indexes are reducing and the ecological environment is not perfect in all the plots, therefore they need further modification and strengthening.
