陕北黄土丘陵沟壑区土被资源利用优化分析——以安塞县为例

The Optimum Utilization Analysis of the Soil Mantle Resource on Hilly and Gully Region of Leoss Plateau in North Shaanxi Province——Taking Ansai County as an Example

本文以陕西省安塞县为例,在土被结构研究的基础上,进行了土被质量评价,并按照土被特征和自然条件把该区分为4个土被生态区。结合生活需求、经济发展和水土保持,利用线性规划方法,分区进行了农业发展优化分析。分析结果表明:在满足生活和环境保护的前提下,该区经济发展具有一定潜力。最后,按照土被类型的镶嵌模式进行了农业生产配置。

In this paper, the qualities of the soil mantle types has been evaluated in Ansai county, Shaanxi province on the basis of a study of soil mantle structure. Thus, the area has been divided into four ecological districts according to its soil mantle features and natural conditions. The argricultural development for every district has been optimized with linear planning (LP) to meet the needs of population, economy, and soil and water conservation. The result shows that the foreground of economic development of the area has much potential after meeting the demands of the population and ecological environment. Meanwhile, the disposition of argriculture has been proposed according to the inlay model of the soil mantle structure.
