大九湖国家湿地公园景观生态评价

An evaluation on the landscape ecology in the natural wetland park of Dajiuhu

湿地公园景观格局是不同类型、不同大小、不同形状的地块在空间上构成的镶嵌体。景观镶嵌结构的差异反映出不同的功能。通过计算一些景观指数,对大九湖湿地公园景观格局作出定量分析。结果表明:①林地占研究区总面积的47.55%,因其面积最大而成为整个景观的基质;②人类不合理的开发利用严重破坏了湿地功能;③人类活动强烈的景观要素中,表征复杂的景观指数较高。

The different type, different size, different shape land parcels constitute the landscape patterns of the wetland park. The difference of landscape reflects the different function. Through calculating some landscape indexs,we make the quantitative analysis to the landscape patterns of the Dajiuhu wetland park. The result indicated that forest occupys 41.65% of the totle study area, it is the matrix of the whole landscape because its area is the most, the wrong developing way destroyed the wetland seriously, where the humanity housing, producing, the landscape indexs which attributes the complexity are higher. These targets can reflect the landscape ecology patterns . They have some instruction function in analysing the landscape ecology steady state on the researching place.
