- 摘要:
- 结合RS和GIS提取西藏普兰县土地覆被类型，以FRAGSTATS提取主要景观指数，运用生态位态势理论，对县域的农业、林业、牧业三大主要覆被景观的经济生态位与景观结构生态位进行了评价分析。结果表明，普兰县以裸岩为基质景观，维持全县生物多样性及生态系统健康的主要是草地与灌木林地景观；生态位态势理论对土地覆被景观的评价体现出了自然和人为作用下，各种土地覆被景观在县域内所形成的不同生态和经济地位；普兰县裸岩的景观生态位最高，它在全县所占面积比例最大决定了其生态最稳，耕地半自然景观在有人为合理干扰条件下，在具有最低的景观结构生态位基础上却能产生较高的经济效益。
- Abstract:
- The land cover map and database of Burang county are worked out by combining remote sensing and geographic information system. This article computes economic niche and landscape structure niche of agriculture, forestry and animal husbandry based on the theory of ecological niche concept as well as eight landscape indexes by aid of Fragstats module. It is summarized that rock is the background landscape which influences the ecological system health of Burang county, while natural grasslands and shrubs landscape are the main landscapes to maintain biologic diversity and ecology system health. The application of ecological niche theory to land cover embodies the ecological and economic niche of different landscape in Burang county by mutual functions of nature and society. Rock landscape is in the most stable state for it accounts for about 40% area of whole county. And tilth landscape have higher economic niche on the reasonable human interference though it has the lowest structure niche.
