| 摘 要： | 利用地理信息系统技术来进行退耕还林(还草)决策分析,能够将多源数据进行叠加分析,利用较少的人力物力就能达到预期的目的,同时提供表格和图形2种数据。以浙江省仙居县城关镇为例,利用GIS技术,分析了这一地区生态退耕还林(还草)地土地数量及空间分布,和以往一些研究的区别在于分析过程中,采取了大比例尺,使小地形也能够得到反映,保证了一定的精度,希望能给退耕还林(还草)工作提供参考作用。

| Abstract: | In using GIS technology to help make decisions about where trees or grass need to be planted, we can overlay all sorts of data and analyse the overlain results with little manpower and material resources. Furthermore this process can provide us with two kinds of data such as tables and figures. Taking Xianju county of Zhejiang province as an example, the suitable places for returning land to forestland or grassland are selected and formulated on the basis of the obtained knowledge. The difference between this and some previous research before is that this work adopted maps of large scale. In this way, small terrain features are reflected and precision is improved. It can provid reference material for similar work on data analysis and selection of suitable places for returning land to forestland or grassland. |
