基于土地利用规划数据库的县域生态环境效应评价——以贵州省岑巩县为例

Eco-environment Effect Evaluation in County Leve Based on the Land Use Planning Database:a case in Cengong County

从土地利用规划数据库成果的应用原理出发,以贵州省岑巩县土地利用规划数据库为数据源,选取景观格局指数分析法对土地利用规划实施产生的生态环境效应进行评价.结果表明,岑巩县土地利用总体规划的实施对生态环境影响微弱,但是从个别地类的长远发展来看,仍需加强法律法规政策的引导,使生态环境在规划期内得到有力的保护.

Based on the data base of land utilization plan and application principle of the plan- ning database results, the effect of eco--environment was evaluated by using the landscape pat- tern index analysis. The results showed that the spatial pattern change of farm land ameliorate the eco--environment, at the same time, the expansion of construction land released negative effect to the eeo--environment, and ecological service value of other land dropped a bit during the planning period.
