Evaluation Method of Cultivated Land-scaled Consolidation Potential Based on Landscape Pattern Principle
摘要
Abstract
In this paper,eight indexes such as altitude,relief amplitude,patch area and extra,from two perspectives of terrain conditions and landscape pattern,have been selected to structure the potential evaluation index system of cultivated land-scaled consolidation.In order to provide a scientific basis for future regional land consolidation,Pingshan County is selected as the study area,and the complexity of cultivated land-scaled consolidation at village level is studied under the spatial analysis function of ArcGIS,and the limiting factors of cultivated land-scaled consolidation is analyzed by using the obstacle diagnosis method.The results show that the cultivated land-scaled consolidation potential index value distributes in [0.12,0.9],and differs greatly in villages.Furthermore,the index value increases overall from the northwest to the southeast.The partition results of cultivated land-scaled consolidation show that the cultivated land in the quaternary area is the largest (51.2％) and in the tertiary area is the second largest (21.3％).The total cultivated land area of the quinary area and the second area is equal to the tertiary area.The cultivated land in the first area is the least (0.9％).The greater degree of partitions is,the easier cultivated land-scaled consolidation is.When consolidation becomes easier,the major obstacle factors of cultivated land-scaled consolidation change from RI and RDLS to CI and RI.关键词
