【摘要】：在城镇化进程中,协调好农村建设用地与地域生态系统之间的关系,推动低效农村建设用地的有效整合,是土地整治工作的关键所在。本文以北京市门头沟区为例,通过构建国土空间生态重要性评价体系,将门头沟区国土空间生态重要性划分为极重要(458.00km~2)、重要(611.37km~2)、一般(379.86km~2))三个级别,以此作为识别门头沟区国土生态安全的健康底线。依据农村居民点综合发展程度评价体系,将门头沟区农村居民点发展程度划分为高发展程度(433.91hm~2)、中发展程度(448.63hm~2)、低发展程度(169.51hm~2)三个级别。通过搭建互斥性组合矩阵,结合不同发展程度的农村居民点所处的生态重要性区间,将区域农村居民点归并为积极发展、限制发展、转型发展、退出利用四种类型,提出不同类型农村居民点的调控发展方向。最后,依据退出利用农村居民点的景观格局特征和空间邻接特征分析,提出山区废弃农村居民点的"精明退出"路径。研究结果有助于实现山区村庄的合理布局和资源的优化配置,对于促进山区经济社会与生态环境的协调发展具有积极的现实意义。
[Abstract]:In the process of urbanization, coordinating the relationship between rural construction land and regional ecosystem and promoting the effective integration of inefficient rural construction land is the key to land renovation. Taking the Mentougou district of Beijing as an example, by constructing an evaluation system of the ecological importance of land and space, this paper divides the ecological importance of land and space in Mentougou into three grades: extremely important (458.00 km2), 611.37 km2 (2), and (379.86 km) (2). This is to identify the Mentougou area land ecological security of the health of the bottom line. According to the comprehensive development evaluation system of rural residential area, the development degree of rural residential area in Mentougou district was divided into three grades: high development degree (433.91hmGN), middle development level (448.63hmmmc2n), and low development level (169.51hmt2). By building mutually-exclusive combination matrix and combining the ecological importance interval of rural residential areas with different development levels, the regional rural residential areas are merged into four types: positive development, restricted development, transformation development, and withdrawal from use. The development direction of regulation and control of different types of rural residential areas is put forward. Finally, according to the analysis of landscape pattern and spatial contiguity characteristics of rural residential areas, the "smart exit" path of abandoned rural residential areas in mountainous areas is put forward. The research results are helpful to realize the rational distribution of mountain villages and the optimal allocation of resources, and have positive practical significance for promoting the coordinated development of economic, social and ecological environment in mountain areas.
