摘要
本文是“京津唐地区(包括秦皇岛市)国土卫星像片在森林资源调查中的应用研究结果的一部分,统计分析了各类森林资源的分布面积和主要特点,并指出其发展潜力,全区现有森林面积计约61.6×10~4 ha,覆盖率约11％,宜林地面积约86.2×10~4 ha,覆盖率约15.4％。主要分布于山地。从发展潜力看,可以增加森林覆盖率10％以上,可能提高立木蓄积量和果树产量4—5倍。
This paper is a part of the results of applying Chinese Territory Scatellite (CTS) materials to investigate forest resources in the Beijing-Qinhuangdao region. It has computed and analysed the distribution areas and main features of every type of forest resources and pointed out their development pontential. Statistics tell that the total area of forests is about 616 thousand hectares and the cover degree is about 11%. The forests are mostly distributed on mountains. But there are many lands suitable for afforestation. Such lands reach 862 thousand hectares and are distributed mainly on lower hills and in plains. The development potential is rather high as it may increase the cover degree of forests by more than 10% and their productivity by about 4-5 times.
