RS与GIS支持的洪湖湿地景观格局分析

Landscape patterns in Honghu wetland using RS and GIS.

利用3S技术对洪湖湿地结构类型进行监测及对洪湖湿地景观格局进行定量分析结果表明,洪湖湿地景观类型所占比例有一定差异,景观多样性指数和均匀度指数较低,景观为少数湿地类型所控制,破碎度指数较小,且景观受人为干扰程度不十分严重,但也不容乐观。

By making use of the 3S technology,the actualities of Honghu wetland configuration and wetland type were investigated. The area of every type of wetland was calculated. Then, the landscape patters of Honghu wetland were analyzed in a quantitative way. The results show that the percent of every type of the wetland landscape has some difference. Diversi- ty and equality of landscape are low. And most of the areas are controlled by only a few type of landscape. The degree of fragmentation and disturbance by people are not heavy.
