龙珠河流域地表覆盖景观格局分析研究

基于遥感和GIS技术,利用最新地理国情及水利普查数据,通过景观格局指数评价体系分析计算了华宁县龙珠河流域地表覆盖和景观的分布、斑块特征、异质性以及多样性等特征.研究结果表明,其地表覆盖景观格局以林地、耕地为主,园地、水体和道路因受人为控制而具有较好的稳定性.流域整体受人为影响较大,景观破碎程度低,自然环境保护较好,这为政府或相应部门掌握该流域内地袁覆盖、自然生态、自然资源状况、将获取到的地理国情信息为常态化的地理国情监测奠定基础.

Analysis on Land Cover Landscape Pattern of Pearl River Basin

Based on the technology of remote sensing and geographical information system,the characteristics of distribution,patch,heterogeneity and diversity of land cover landscape in Huaning County Pearl River basin were analyzed and calculated by using the latest data of geographic condition sand water resources census information and evaluation system of landscape pattern index.The result showed that,the landscape pattern of land cover mainly on forest and cropland,also land,water and roads owing to human control has strong stability.Whole basin greatly influenced by human activities,and the degree of fragmentation of the landscape is low,the protection of natural environment is well.The research result of this paper is good for the government or the relevant department to grasp the situation of area cover,natural ecology and natural resources in the basin,besides get to the geographical of information to lay the foundation for the normalization of geographical condition monitoring.
