摘要: 以三峡库区(重庆段)的遥感解译数据为基础,将研究区域划分为3 175个4×4 km的评价单元,基于景观生态学和土地利用系统特性,构建了土地 利用空间冲突测度模型,以评价单元的土地利用空间冲突测度值为依据划分了4种冲突类型,最后对研究区域土地利用空间冲突的驱动因子进行主成分分 析。结果表明:研究区域的空间冲突在研究时段内整体处于较为严峻状态,重度冲突和中度冲突占比达到55%以上;从空间分布来看,土地利用空间冲突 高值区集中在东北和西南区域,并随着时间推移从东北区域向着西南方向转移,最后以西南地区的主城区为中心向外扩张,一般冲突和轻度冲突类型则分 布在最北端和东南部的边缘地带;1990—2010年的变化趋势显示部分中度冲突类型转化成了重度冲突类型,表明研究区的土地利用空间冲突在不断加强, 冲突地类从林地、草地转换成了湿地、耕地和建设用地;三峡库区(重庆段)的土地利用空间冲突驱动因素可概括为经济发展、人口增长压力和三峡工程 建设。

Abstract: Based on the remote sensing interpretation data of the Three Gorges Reservoir area (Chongqing section), the study area was divided into 3 175 4×4 km evaluation units, and a spatial conflict measurement model for land use was constructed on the basis of the characteristics of landscape ecology and land use system. Four types of land use spatial conflicts were classified on the basis of the spatial conflict measurement value of the evaluation unit. Finally, the principal component analysis was carried out on the driving factors of the land use space conflict of the study area. The results show that: 1)the spatial conflict in the study area is in a rather severe state during the study period, and the proportion of the severe conflict type and the moderate conflict type is over 55%. 2) From the point of view of spatial distribution, the high value area of land use spatial conflict is concentrated in the northeast and southwest regions and it shifts from the northeast to the southwest, with the passage of time. Finally, it expands outward with the main urban area in southwest China as the center, while the types of general and minor conflicts are distributed in the northernmost and southeastern fringes. 3) The change trend from 1990 to 2010 shows that some moderate conflict types have been transformed into severe conflict types, indicating that the land use space conflicts in the study area are continuously strengthening, and the conflict areas are converted from woodland and grassland to wetland, cultivated land and construction land. 4) The driving factors of space conflict in the Three Gorges Reservoir area (Chongqing section) can be summarized as economic development, population growth pressure and the construction of the Three Gorges Project.
