县域森林破碎化评价是对生态建设的重点区域和森林植被发生变化的热点区域进行判读区划和测定分析。以云阳县为例，利用2002年森林资源调查数据，结合2006，2011年两期 SPOT 5影像开展判读区划，对比分析3期森林分布数据，运用 ArcGis 10.0和 Fragstars 4.0软件，选取合适的景观格局指数，对云阳森林景观破碎化及其驱动力进行分析。结果表明：全县森林破碎化程度明显减轻，局部区域小片林及林带多，森林破碎化严重；工程造林与社会政策是驱动云阳县森林景观破碎化减轻的关键因素，其中退耕还林工程造林贡献最大；农业活动与城镇建设是制约云阳县森林景观破碎化逆转的主要因素，应进一步加强林地保护管理，减少森林流失，建设健康稳定的森林生态系统。

The evaluation of forest fragmentation is interpretation and analysis division in key forest vege-tation ecological construction area and hot spots of forest vegetation change.In this paper,the forest distri-bution data were derived from interpreting the SPOT5 images of 2006 and 2011 based on forest inventory data in 2002 in characterize the status of forest fragmentation and its driving forces since 2002 in Yunyang country,applying the packages of Arcgis10.0 and Fragstats 4.0.Diminishing of fragmentation status at county level is significant.On the contrary,negative trend exists in partial areas due to a number of small stands and narrow gallery forest.Project afforestation and social policies are the key driving forces to ac-celerate forest landscape fragmentation alleviation.On the contrary,obvious deforestation and land occupa-tion for agricultural use and urban construction are direct deterrent factors of reversed forest landscape fragmentation in the study area.It is urgent to strengthen forestry land protection and management and re-duce forest loss aiming at establishment of healthy and stable forest ecosystem in Yunyang country.
