[Spatial diversity index analysis on wildlife habitat pattern change in the Liaohe Delta].
Based on the study of land cover change in the Liaohe Delta with GIS and RS, the wildlife habitat pattern was described quantitatively, and the pattern change between 1988 and 1998 was analyzed with spatial diversity index. The results showed that the wildlife habitat pattern had an obvious change during the ten years caused by natural and human disturbance. The area of suitable habitat(Sd > or = 0.35) was becoming smaller and more fragmented, with a deteriorated quality. It was proved that spatial diversity index could reflect the habitat suitability of wildlife, and describe the habitat spatial pattern explicitly. This study would provide a scientific basis for protecting wild animals and their habitats.
