基于GIS的景观生态规划研究——以二龙山水库流域景观生态系统为例

运用地理信息系统 (GIS)技术强大的信息管理、空间数据处理分析功能 ,采用松散耦合式GIS建模方式 ,在景观格局分析的基础上 ,对二龙山水库流域退化生态系统进行景观生态规划 ,期望通过对原有的景观要素的优化组合或引入新的成分 ,调整或构造新的景观格局 ,以增加景观的异质性和稳定性 ,为二龙山水库流域退化生态系统的恢复和重建提出建设性的意见 ,为可持续的景观管理模式提供理论依据。

Study on Landscape Ecology Planning with GIS--Taking Erlongshan- Reservoir-Valley Ecosystem as an Example

This paper applied GIS technology's powerful function of information management and spatial data disposal or analysis, adopted incompact coupling GIS modeling method, and took the region-landscape ecological system as target, conducted quantitative and locational research to discuss and reveal the relationship between landscape pattern ,based on the results of landscape pattern analysis.This paper attempted to add the landscape's heterogeneity and stability by optimizing and combining the landscape elements, adjusting and building a new landscape pattern, and finally designed a more efficient and harmonious ecosystem of manmade-nature landscape which is superior to the primary in the way of economic and ecological benefit . This paper would provide some constructive proposals for restoration and rehabilitation of Erlongshan- Reservoir-Valley degraded ecosystem, and the theoretic basis for establishment of sustainable landscape-management pattern
