基于生态规划理念的三峡库区土地利用结构分析

Land Use Structure Analysis Based on Ecological Concept in the Three-Gorges Reservoir Area

根据第二次全国土地调查数据,采用多样化指数、优势度指数、集中化指数、组合类型、区位指数等多个生态学指标,对地处三峡库区腹地的丰都县沿江10个乡镇的土地利用结构进行定量分析。结果表明,该研究所选取的生态学指标间呈现有规律的相关性,且能很好地揭示区域土地利用现状特点。在土地利用规划中应该加强生态规划理念,采用生态学方法对土地利用结构进行分析,为土地利用规划后续工作提供导向作用。

According to the second land investigation data,several ecological indexes,such as diversity,dominance,concentration,combination type and location index were adopted to analyze the land use structure of 10 towns in Fengdu County.As indicated by the result,these indicators have correlativity between each others and could well reflect actual characteristics of the present situation of land-use in this area.It was considered that ecology idea should be strengthened in land-use planning and the ecological methods can be applied to land-use structure analysis with the aim of providing ecological concept guidance for the follow-up work of land-use planning.
