摘要
通过对比分析杭州市森林资源动态监测数据与土地调查成果,探讨林业专项数据中林地及重要森林资源与土地调查成果的差异化程度、差异分布及差异产生的原因,为加快杭州市林业专项纳入现行国土空间规划体系提供科学依据。结果表明,杭州市森林资源动态监测数据与土地调查更新成果的地类一致性整体较高,平均达到88.06%。差异图斑以集体林,人工林,商品林和低保护等级的林地为主,但国有林,天然林,重点公益林等重要森林资源的差异总面积依然庞大,是需要林业部门重点关注的几大类型。
This paper assessed the differentiation degree and distribution of forest resources between forest resources dynamic monitoring data(FRD)and national land survey data(LSD)in Hangzhou,and then analyzed the causes of data difference.The results showed that the overall consistency between FRD and LSD was relatively high,reaching an average of 88.06%.Difference map showed that most of the differences were collective forests,plantations,commercial forests and forests with low protection level.However,the total difference area of national forests,natural forests and public welfare forests were still quite large,which needed close attention by the forestry authority.
