三峡库区森林景观空间格局定量分析

Quantitative Analysis of Forest Landscape and Spatial Pattern in Three Gorges Reservoir

摘要:

摘要：根据三峡库区森林资源二类调查数据库，借助GIS平台构建森林景观空间格局分布图，通过对林分水平与区域水平的景观空间格局特征指数的定量描述和分析，揭示该区域森林生态系统环境状况及空间变异特征，有助于从宏观角度理解区域生态状况，辨识已发生或可能发生的各种变化，并作为早期预警和诊断性指标，为制定区域林业可持续发展的宏观政策提供科学依据。

Abstract:Based on the GIS platform and by taking full use of the historical data of national forest resources investigation, the quantified evaluation on the structure, function, stability of forest resources in Three Gorge Reservoir was given at forest level and regional level respectively. The quantified description on the landscape index in Three Gorge Reservoir was not only the basis for the evaluation on current status, but also the basis affecting the forecast; furthermore, it was the existing issue eagerly needed to be addressed in the plan and decision process for the management of forest ecosystem health.
