摘要

[目的]明确山地丘陵区土地整治项目的覆土区域，指导项目区域的规划设计。[方法]选取涉及土壤构型、交通状况、立地条件、土壤理化性质等方面的7个指标，利用GIS技术，对陕西省铜川市一典型土地整治项目进行覆土优先度评价。[结果]①项目区内I级覆土需求优先度区域占到田块总面积的46.2%，其覆土的综合效益较大，可优先安排覆土；②Ⅱ级覆土需求优先度区域占田块总面积的23.7%，可根据土源情况适当进行覆土；③Ⅲ，Ⅳ级覆土优先度区域共占到田块总面积的30.1%，此2个区域覆土效益较小或基本无覆土需求，可不进行覆土。[结论]评价结果明确了各个区域的覆土需求度，较好地反映了土地整治项目区的真实情况。

Abstract

[Objective] To determine the area of soil covering

in order to guide the planning and designing in hilly area land reclamation project.[Methods] Using GIS technology

seven indicators including soil construction

traffic condition

site conditions

soil physical and chemical properties were chosen to evaluate the priority of soil-covering demand of a typical land reclamation project in Tongchuan City

Shaanxi Province.[Results] ① The grade Ⅰ priority of soil covering demand of farmland accounted for 46.2% of the total area of the field. The comprehensive benefits of covering soil were high and should be covered by soil preferentially. ② The grade Ⅱ priority of soil covering demand of farmland accounted for 23.7% of the total field

where the covering soil should be made practically according to soil source. ③ The region of grade Ⅲ and grade Ⅳ totally accounted for 30.1% of the field

which had less benefit or necessity of covering soil.[Conclusion] The evaluation results reflected the fact in land reclamation project area and classified the demand of covering soil

which could provide the theoretical foundation for the design and engineering practice.
