摘要:

以村庄为基本单元,结合实地调研和村庄级统计材料,收集门头沟区18条典型沟域的沟域经济发展数据。在对其沟域经济类型区进行研究的基础上,对地域类型进行了划分,并探讨了不同地域类型下的沟域经济空间结构。根据熵权—层次模型,结合实地调研数据、专家意见及村庄级资料,研究得出沟域平均海拔、区位条件等是沟域经济地域类型划分的主导要素。在地域类型上,可将门头沟区沟域经济划分为山前型(平均海拔400 m以下),浅山型(平均海拔600 m以下),近深山型(平均海拔1 000 m以下)和远深山型(平均海拔1 000 m以上)等4种地域类型。在空间结构上,门头沟区4种地域类型的沟域经济各具特征,山前型沟域具有网络式空间结构(山前网络型),浅山型沟域具有点轴式空间结构(浅山点轴型),近深山型沟域具有据点式空间结构(近深山据点型),远深山型沟域具有相对均衡式空间结构(远深山相对均衡型)。

Abstract:

Geographic types are relative stability region units, which are formed in the certain geographical environment and a long history process, and composed by many special areas or units that have similar features in development conditions, production structure, development characteristics, development direction, and etc. The valley economy, as a new model of mountain development, is playing a more and more important role in gathering and effective linking in the mountainous traffic, villages, population and resources, which meets the requirements of mountainous space optimization development. By now, there are a little of achievements in the study of valley economy′s geographic type. From the perspective of Geography, valley economy′s geographic type identification has a great theory significance and practical value, which can provide some references for mountainous areas′ development. Mentougou, in the west of Beijing, is situated in the transitional mountainous areas of Mongolian plateau and North China plain, the intersection of platform anteclise in Shanxi Provinceand Yanshan fold belt. The mountainous areas occupy 98.5% of the study area, approximately 300 valleys here, thus it can be regarded as the pure mountainous area in Beijing. Mentougou possess the typical characteristics of valley economy development. Taking villages in Mentougou as the basic units, combined with dates from field research and village-level statistics, valley economy materials of 18 typical valleys in Mentougou district are gained. Based on the division of valley economy geographical zone, this paper identified its geographic type, and probed the spatial structure of different valley economy geographic types. According to the identification model, based on entropy weight theory and AHP method, combined with field research dates, expert advices and village-level statistical materials, this study obtained that, valley average elevation is the dominant factor to identificate valley economy geographic type. In geographic type, combined with analysis on the topographic profile, the Mentougou valley economy can be divided into piedmont type (≤400 m), shallow mountain type (≤600 m), appro-alpine type (≤1000 m) and far-alpine type (>1000 m). In spatial structure, the 4 valley economy geographic types have their own features: piedmont type valley possesses a network spatial structure (piedmont network type), shallow mountain type valley possesses a point-axis type spatial structure (shallow mountain point-axis type), appro-alpine type valley possesses a base type spatial structure (appro-alpine base type), and far-alpine type valley possesses a relative balanced type spatial structure (far-alpine relative balanced type).
