摘 要：
区域水土资源综合质量评价是开展区域农业种植结构调整、资源优化配置和合理开发利用的基础。为促进黑龙港地区水土资源与区域经济协调发展,基于熵值赋权法,利用ArcGIS 10平台,将区域水资源与土地资源作为统一的系统,开展了单位像元尺度的水土资源综合质量评价。评价结果显示,黑龙港地区水土资源综合质量较低,多数地区综合质量值处于0.4～0.6之间,0.6以上相对优良区面积仅占总面积的2.5%,黑龙港地区总体趋势呈现中间及南部区域水土资源综合质量值较高,而东西两侧的边缘区域质量较低。研究结果还表明,在土壤资源质量相对差的区域,如果水资源质量较好,则土壤资源将被改良,区域水土资源综合质量也得以提升。

摘 要：
Comprehensive assessment on the quality of soil and water resources provides a base for structure adjustment of agricultural planting and optimal allocation of soil and water resources.In order to promote the wise-use of soil and water resources and economic development in Heilonggang area,the comprehensive assessment was carried out at pixel scale on the ArcGIS 10 platform.The evaluation results showed that the quality of the soil and water resources in Heilonggang area was low,with quality values varying between 0.4-0.6.Only 2.5% of the total area had a quality score higher than 0.6.Spatially,the middle and southern regions had high quality resources,and the resources of the eastern and western edges of the study area were of lower quality.The results also showed that the soil resources that had relatively poor quality at present could be improved if water quality became better and at the same time,regional integrated quality of soil and water resources could be raised.
