摘要

针对黄土高原上黄试区自身特点

结合专家评议

建立了该区土地利用适宜性评价指标体系。采用专家打分法对各指标进行量化分级与权重确定。运用ArcView 3.2软件将该流域划分为185个地块

并建立各地块的空间和属性数据库。利用软件的空间叠加分析功能与综合指数法研究了各地块土地利用的适宜程度。结果表明:上黄试区宜牧地面积最大

约为419.04hm

(52.31%);宜农地次之

约为195.35hm

(24.39%);宜林地面积最小

仅为46.8hm

(5.84%);宜林牧土地面积约为139.86hm

(17.46%)。评价结果可为上黄试区最佳土地利用方案的确定提供数据基础。

Abstract

An assessment index system of land use suitability in the Shanghuang experimental area was established based on the characteristics of the area and the experts'advices

and the quantitative grade and weight of each index for the land suitability assessment were acquired using expert scoring method.The experimental area was divided into 185units

and the spatial and attributive database of the 185units were established using ArcView 3.2software.The land use suitability of each unit was analyzed using spatial overlay analysis function and comprehensive index method.Results showed that the largest area in the experimental area was the land suitable for grassland

about 419.04hm2(52.31%);the second

for agriculture

about 195.35hm2(24.39%);and the smallest

for woodland

about 46.8hm2(5.84%).the area of the land suitable for both grassland and woodland was 139.86hm2(17.46%).Result from the assessment could provide a data basis for determining the best land use plan of the experimental area.
