摘要

耕地集约利用内涵界定是耕地集约利用评价的基础。分析了耕地集约利用的内涵

构建了黑龙江省耕地集约利用指标体系

运用信息熵、综合指数和GIS相结合的方法对黑龙江省耕地集约利用空间差异状况进行了分析。结果表明

黑龙江省耕地集约利用水平受区域自然条件差异影响

具有明显的区域分异特征

表现为黑龙江省西南部和南部地区耕地集约利用程度高

东部地区次之

北部和西北部地区最低;从指标体系领域层权重看

投入强度对耕地集约利用水平的影响最大

对耕地的基础设施投入远低于生产性投入

从而为黑龙江省区域耕地投入政策制定和调整提供依据。

Abstract

The definition is the foundation of the assessment of intensive use of cultivated lands.The study developed an indicator system for cultivated land intensive use in Heilongjiang Province.With calculations of entropy and composite index and support of GIS

this study analyzed the spatial difference in intensive usage of the cultivated land.The result shows that

the intensive use level of the cultivated lands displayed obvious regional differentiation characteristics

influenced by the natural conditions of the regions.The cultivated lands in the middle and south parts of the study area had the highest intensive degree

those in the east and west were lower

and those in the north were the lowest.In terms of the weights of the indicators

the investment intensity was most important factor in evaluating intensive use of cultivated land.The farming infrastructure investments in the study area were substantially lower than the production investment.The findings of the project provide the basis for policy making and adjustment of farming investment in the area.
