| 摘 要： | 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。

Application of the 3S Technologies in the Monitoring of Forseted Land Changes in and around the Nature Reserves |
| |
| Abstract: | To monitor forestland resources changes both in Caiyanghe Nature Reserve and its adjacent zone, 3S technologies are applied in forestland resources inventory It turned out that forestland is shrinking, none-forestland is expanding, forested area is expanding, forest is shrinking, economic forest is expanding, land suitable for forest is decreasing and forest coverage is increasing, bio-diversity related is diminishing and eco-benefit is diminishing The results are also in line with practical situations |
