生态空间科学合理识别是区域生态保护的基础.以国家重点生态功能区中三峡库区水土保持生态功能区———长阳土家族自治县为案例区,借助于RS和GIS技术方法,因地制宜地选取指标进行生态功能重要性和生态敏感性评价,对生态空间识别进行研究,并简要提出了分区分级管控生态空间的思路,最后结合现状土地利用类型对生态空间土地利用冲突进行分析.结果表明:1)长阳县生态空间总面积为3 032.21 km~2,占研究区总面积的88.66%,其中底线型、危机型和缓冲型生态空间面积分别为1 406.79 km~2、862.59 km~2和762.83 km~2,分别占研究区总面积的41.14%、25.22%和22.31%.2)在现状土地利用类型分析中,约有17.11%的耕...

Ecological space is of great significance for maintaining regional ecological security and ecological balance,so the identification of ecological spaces is the basis of regional ecological protection.Taking the soil and water conservation ecological function zone of the Three Gorges Reservoir Area in the national key ecological function region as the case area,the Changyang Tujia Autonomous County is used as a case study.According to local conditions,the evaluation indicators were selected,and spatial information technology based on RS and GIS were used to evaluate the importance of ecosystem ...
