摘要
基于MapInfoProfessional 6 .0软件和野外调查所积累的资料 ,首先找出最佳“投资 效益比”的珍稀濒危物种密集分布区。随后 ,利用GAP分析的方法 ,对龙门河地区现状植被类型图、管理规划图、珍稀濒危物种密集分布区图进行了叠加分析 ,结果表明 :该地区规划管理的gap主要由 3部分组成 ,即原管理方法中不限制人为干扰的区域、原保护区域内没有包含的自然植被类型所属分布区、珍稀濒危物种密集分布区中没有禁止人为干扰的区域。其总面积为 1 736hm2 ,占龙门河地区总面积的 36 .81 %。综合考虑对植物多样性的保护及当地居民的生活所需 。
On the basis of sufficient plant community survey and quantitative analysis of vegetation environment at Longmenhe region, we seeked the richest area for rare and endangered species using MapInfo Professional 6.0 software firstly. We then applied the GAP analysis methodology to compare the vegetation, the management and the dense distribution area of rare and endangered species status layers. The result shows that the GAPs for planning and management in this area consist of three parts: 1) the area that human interventions are not prohibited in current management practice; 2) the area where developed some natural vegetation types which are not found in current protected area; and 3) the dense distribution area of rare and endangered species that man_made disturbance is not prohibited currently. The area of GAPs is about 1736 hm 2, accounting for 36.81% of Longmenhe region. Considering biodiversity protection and living standard of local communities, we suggested a number of priority areas for the management of this region.
