汶川县生物多样性保育与区域发展的综合地域划分

依据生物多样性和社会经济发展方面的 2 0个指标 ,应用模糊聚类算法对汶川县的综合地域划分研究表明 ,汶川县可以划分为 4个综合地域类型 :发展主导型 (Ⅰ ) ,占县域面积的4 3% ;特色开发型 (Ⅱ ) ,占县域面积的 2 3 5 % ;发展支持型 (Ⅲ ) ,占县域面积的 6 5 % ;生态保育和限制性开发型 (Ⅳ ) ,占县域面积的 6 5 7%。县域水平上协调生物多样性保育和区域发展关系的空间策略是东西分治 ,东部 (Ⅰ、Ⅱ、Ⅲ )以社会经济发展为主 ,西部 (Ⅳ )以生态保育为主。在区域发展的产业选择上应重视产业的生态化 ,突出地域优势与特色。

Comprehensive regionalization of Wenchuan County on biodiversity conservation and regional development

Regionalization is an important research topic in geography and ecology. The realization of biodiversity conservation and the sustainable development of socio economy must be based on geographical location. County level regionalization can provide support on macroscopic decision making such as land resources allocation, economic development, biodiversity conservation, and industrial development. Based on 20 indicators of biodiversity and socio economic development, this study adopted fuzzy clustering algorithm as the computational tool for the comprehensive regionalization of Wenchuan County. The results indicated that Wenchuan County could be divided into 4 types of comprehensive zones: the Development Dominant Zone(Ⅰ), including Weizhou Township and Xuankou Township, accounting for 4 3% of the total county area; the Development Zone with Local Characteristics(Ⅱ), including Mianchi Township, Longxi Township, Keku Township, Yanmen Township, and Yinxing Township, accounting for 23.5% of the total county area; the Development Support Zone(Ⅲ), including Yingxiu Township, Shuimo Township and Baihua Township, accounting for 6.5% of the total county area; the Ecological Conservation and Restrictive Development Zone(Ⅳ), including Wolong Special Administration for Nature Conservation(WSANC), Caopo Township, and Sanjiang Township, accounting for 65.7% of the total county area. WSANC is the core of Ⅳ with Caopo Township and Sanjiang Township as the buffers. The spatial strategy on coordinating biodiversity conservation and regional development is to develop mainly from the east(Ⅰ,Ⅱ,Ⅲ) and to conserve mainly in the west(Ⅳ). Eco industry, such as eco tourism, eco agriculture, etc., need to be emphasized in the process of regional development.
