摘　　要：以昆明市海口林场遥感影像图、森林资源分布图、地形图及数字化等高线得到的DEM数据为信息源,利用Arc GIS的空间分析功能,选取坡度、距离2个因子对海口林场森林景观的景观视觉敏感度进行评价。结果表明,敏感度最高的一级敏感区面积为1.5 km2,只占林场总面积的1.9%;敏感度次之的二级、三级敏感区面积为34.5 km2,占总面积的46%,但树种结构相对单一;四级敏感区面积为40 km2,占总面积的52.1%,占比最大。基于评价结果,提出海口林场森林景观开发利用建议:采取不同的造林方式,营造疏密有致、色彩丰富的森林景观,同时加强非煤矿山企业的监管,合理规划观景道路,保护景观敏感度高区域,提高森林景观水平。DEM data that came from the remote sensing image, forest distribution map, topographic map and digital contour, was used as information source, combined with ArcGIS spatial analysis function, the landscape visual sensitivity of Haikou Forestry Farm was analyzed and estimated. The results show that the area of the first sensitivity grade is 1.5 km^2 , accounts for 1.9% of the total area; the area of the second grade and the third grade is 34.5km^2, accounts for 46% of the total area, but the structure of tree species is relatively single ; the area of fourth grade is 40km2 , accounts for the largest proportion, reached 52.1%. As a result, some proposals to take a different way of afforestation, to build the density and colorful forest landscape, meanwhile, strengthen the supervision of non -coal mine company, plan the road reasonably, protect the high landscape sensitivity area, and improve the level of the farm＇ s forest land- scape, are put forward.
