辽宁省农用地质量空间分布格局及影响因素研究

采用GIS技术、地统计学分析和景观生态学方法对辽宁省农用地质量的空间分布规律及其多样性、均匀度、集中度、优势度等进行研究,结果表明：辽宁省农用地质量的区域分异明显,等别表现出由辽西低山丘陵区和辽东山地丘陵区向中部平原区的递增规律。探讨农用地质量空间格局的影响因素,发现农用地自然质量空间分布格局主要受到地带性因素与大尺度的非地带性因素的控制,农用地利用质量和经济质量空间分布格局受到人类活动的影响显著。

Spatial distribution pattern of agricultural land resources quality and influence factors in Liaoning province

The paper based on the results of the farmland classification,the quality of agricultural land resources,the spatial distribution pattern and diversity,equality,centrality and superiority of farmland resources quality in Liaoning Province and its influence factors were studied by means of GIS,geostatistics of analysis,landscape ecology.The results shows that the differences of farmland resources quality in Liaoning Province in different agricultural regions are distinct.The grades of farmland resources quality were increase from the western low hills region and the eastern mountains region of Liaoning to the central region of Liaoning province. And we have also discussed the factors affecting spatial distribution pattern of agricultural land resources quality and discovered that the spatial distribution pattern of land natural quality are mainly affected by geographic factors and large scale non-geographic factors and the spatial distribution pattern of land use quality and economic quality are affected remarkable by human activities.
