基于农户视角的耕地景观格局研究

Study on Cultivated Landscape Pattern Based on Household′s Perspective

为掌握农户层面的土地利用现状,基于农用地承包经营权确权成果,采用景观格局指数,从斑块规模、斑块形状以及斑块整体特征3个层面研究分析广东省清远市阳山县七拱镇耕地景观格局。研究结果表明:1阳山县七拱镇农户拥有的耕地斑块数量普遍较少,绝大多数仅有一块,且斑块面积较小,耕地权属过于分散;2农户分散经营下的耕地形状较为规整,权属界线清晰,耕地规模经营的自然潜力较大;3农户间的耕地斑块边缘长度较长,破碎度较高,不利于农业机械化经营。为此,从土地整理、流转经营、规划布局以及农业基础设施建设等方面提出改善耕地经营的对策。

In order to grasp the present situation of land use on the level of farmers,this paper used landscape pattern index to study the landscape pattern of farmland from the patch size,patch shape and plaque integral features three aspects based on the results of agricultural land contracted management fight verification in Qigong Town, Yangshan County, Qingyuan City, Guangdong Province.The results showed that firstly, the cultivated land ownership was too fragmented because the quantity and the area of cultivated land were less. Besides, the cultivated land shape was neat and the ownership boundaries were clear under the decentralized management, so the potential of cultivated land scale operation was large.Thirdly, It was not conducive to the operation of agricultural mechanization as the longer plaque edge length and higher fragmentation.Therefore ,this paper put forward some countermeasures to improve land management, such as land consolidation, circulation management, planning and layout, and agricultural infrastructure construction.
