摘要:

依据华东7省森林资源清查数据,通过地类、林种前后期动态变化的对比分析,得出华东监测区及其各省林地均存在转移出去和转移进来的现象。这种林地与非林地间的转移,绝大部分是在乔木林地、特殊灌木林地、未成林造林地与<25°耕地、建设用地等已开发利用土地之间的转移,用开发未利用地增加林地和提高森林覆盖率已近临界值。林地进出转移最突出的是山东、江苏、河南,安徽、浙江次之,福建、江西轻微。目前华东7省森林覆盖率的消长与林地进出差值呈明显正相关,且林地转移处于进略大于出的近平衡状态,一旦失衡,将对低森林覆盖率的省份产生较大影响。

Abstract:

Based on the research of the forest inventory data of the seven provinces in East China,it was found that forestry land and non-forestry land were transferred into each other with the times.Most of the transfers were between arbor woodland,special shrub land,the immature forestland and the developed land that includes the farmland and the land used for building.The transfers in Shandong and He’ nan provinces were more significant than those in Anhui and Zhejiang provinces,and the transfers were slight in Fujian and Jiangxi provinces.It was a positive correlation between the change of forest cover rate and the number of the above-mentioned transfers.Moreover,the transfers were near balance.Once the balance was destroyed,a significant influence will be exerted to the provinces with low forest cover rate.

Key words: forest inventory, land use type, forestland, transfer, forest cover rate
