- 摘要:
- 退耕还林（草）工程是改善我国生态环境，促进地区经济可持续发展的重点工程和重要途径。尤其在沂蒙山区，多年来由于自然和人为因素的影响，生态环境恶化，严重制约着社会和经济的发展。利用GIS技术，结合退耕还林的基本原则，通过空间分析的研究方法，对土地利用、坡度、河流、居民点等数据进行叠置处理，以获取退耕还林的区域面积。同时对退耕还林的时序及经济林分布问题也作了一定的探讨。结果显示：沂蒙山区坡度>25°需退耕还林的面积为5.47×104 hm2。
- Abstract:
- The project of converting land for forest land and grass land is a great project and important method to improve ecological environment and accelerate economic development in China.Especially in Yimeng Mountains,because the influence of natural and artificial factors,the ecological environment has worsened which restricted the development of society economy.Supporting by GIS technology,using databases of landuse,slope,river,residential point etc,combining the principle of converting the land for forest land and grass land,and through the research method of spatial analysis,the area of converting the land for forest can be got.At the same time,the order of converting the land for forest and the distribution of economic forest are discussed.The result shows that the area of converting land for forest is 5.47×104 hm2 at the slope which is bigger than 25°in Yimeng Mountains.
