摘要/Abstract

摘要： 为测算耕地破碎化程度,分析土地整理对渝西方山丘陵区耕地景观的影响,探讨耕地破碎化的影响因素。从景观方面遴选出平均斑块面积、耕地斑块密度指数、耕地斑块破碎化指数等典型指标,构成耕地破碎化指标体系。结果表明,2012年水头社区的耕地破碎化指数为0.042 3,2017年的耕地破碎化指数为0.036 9,破碎化情况得到了一定程度的缓解;水头社区耕地破碎化的主要特征为受地形因素影响,地势起伏越大的区域,破碎化程度越高;研究区耕地破碎化的主要动因是地形、土地利用政策、水域、道路等因素;地形因素为渝西方山丘陵区耕地破碎化的根本因素,土地利用政策为其破碎化程度降低的有效措施,应积极推进土地整理等政策与措施,积极引导土地流转,统筹城乡发展。

Abstract: To measure the degree of arable land fragmentation, the impact of land preparation on the landscape of arable land in the western hills of Yuxi was analyzed, and the influencing factors of arable land fragmentation were explored. Typical indicators, including average patch area, arable patch density index and arable patch fragmentation index, were selected from the landscape aspect to constitute the arable fragmentation index system. The research results showed that the fragmentation index of arable land in Shuitou community was 0.042 3 in 2012 and 0.036 9 in 2017, and the fragmentation has been alleviated to a certain extent; the main characteristics of arable land fragmentation in Shuitou community were influenced by topographic factors, and the greater the undulation of the terrain, the higher the degree of fragmentation; the main drivers of arable land fragmentation in the study area were topography, land use policy, water area, roads, etc. The topography factor was the fundamental factor of arable land fragmentation in the hilly area of Yuxi, and the land use policy is the effective measure to reduce the fragmentation, and policies and measures such as land preparation should be carried out to actively guide land transfer and coordinate urban and rural development.
