[目的]通过探讨黑龙江省耕地内部的时空变化规律及耗水净量空间变化趋势,为预测黑龙江省耕地的发展趋势和进一步优化耕地内部结构提供一定的理论基础和依据。[方法]采用GIS分析等地理学分析方法,分析1980—2015年黑龙江省耕地内部水田和旱地变换过程,并结合耕地耗水量计算探讨了黑龙江各县级市耗水量增减变化。[结果]在面积数量变化上,近35年来黑龙江省水田面积总体呈现持续上升的趋势,旱地面积则经历了由增到减的过程。在空间分布变化上,黑龙江省1980—2015年水田和旱地空间变化都经历了由分散到集中的过程,主要变化区域集中于三江平原和松嫩平原。耗水净量方面在三江平原地区一直处于高水平阶...

By discussing the spatial and temporal variation of the cultivated land in Heilongjiang province and the spatial variation trend of the net water consumption,this study provides a theoretical reference and basis for predicting the development trend of cultivated land in Heilongjiang province and further optimizing the internal structure of cultivated land. It used GIS analysis and other geographic analysis methods to analyze the transformation process of paddy field and dry land in cultivated land of Heilongjiang province from 1980 to 2015. Combined with the calculation of water consumption of...
