黄山市土地利用变化的生态环境效应研究

Study on the Effect of Land Use Change on the Eco-environment of Huangshan

随着人口的增加及经济的发展,人类对土地利用模式的改变更为显著,导致了土地资源生态环境背景的变化。对黄山市1987年和2000年土地利用变化的生态环境效应进行研究,结果表明:(1)黄山市部分地区森林破坏相对严重,生态功能有所衰减。(2)水土流失日趋严重,危害性越来越大。(3)部分水体污染加重,水质开始恶化。

With the increase of population and the development of economy,the land use change is more notable,and causes the change of eco-environmental background of land resources. Studying the effect of land use change on eco-environment can improve the conditions of agricultural production,and make the regional economy and eco-environment develop in a good way. Taking Huangshan as an example^the pattern of land use change is analyzed and the result shows that there is an obvious decrease in the area of plantation and forestland in Huangshan City,while rural residential land and building sites and grassland increasd in 1987 and 2000. Then the effect of land use change on the eco-environment is studied. At last,four suggestions about protection and control are given.
