为了监测保护区及周边地区的林地资源变化情况,利用“3S”技术对菜阳河自然保护区及周边地区的林地资源变化进行了调查,结果为:林业用地面积减少,非林业用地面积增加;有林地面积增加;林分面积减少;经济林面积增加;宜林地面积减少;森林覆盖率增加,生物多样性附着能力减弱,生态效益降低。调查结果符合实际情况。
In order to monitor the change of forestland resources in the reserve and the surrounding area, the “3S” technology was used to investigate the change of forestland resources in Caiyanghe Nature Reserve and the surrounding areas. The results showed that: the area of forestry land decreased and that of non-forestry land Increase; the area of forest land increased; the area of forest stand decreased; the area of economic forest increased; the area of suitable forest land decreased; the forest coverage rate increased, the attachment ability of biodiversity decreased and the ecological benefit decreased. The findings are in line with the actual situation.
