以洞庭湖区为研究对象,在3S技术支持下,利用生态系统服务功能量评估法、生物多样性综合指数评价法及形态空间格局分析法对绿地生态关键区进行综合识别及特征分析。结果表明:洞庭湖区绿地生态关键区空间分布不均衡,其主要分布在研究区的西北部、西南部、东部、中部;由林地、灌丛、园地、草地、水域构成,其中林地面积为8 415.18 km2,灌丛面积为3 410.31 km2,水域面积为1 922.27 km2,这三者面积之和为绿地生态关键区总面积的95.90%,为研究区总面积的30.32%;关键区中的林地与灌丛的平均海拔高度分别为371.6、402.6 m,主要位于研究区内的山区,生物资源丰富;关键区中的水域平均海拔高度为33.5 m,主要为...

Taking Dongting Lake region as an example,with the support of 3S technology,identified the key areas of green space ecological network and analyzed their features with the methods of comprehensive evaluation of ecosystem service,comprehensive evaluation of biodiversity index and morphological spatial pattern analysis.The results showed that the spatial distribution of the key green space ecological areas in Dongting Lake region was unbalanced.They were mainly distributed in the northwest,southwest,east and middle of the study region.It consisted of forest land,shrub land,orchard land,grass lan...
