新疆生态保育与重建区划图的设计与编制

Design and Establishment of the Regionalization Map of Ecological Conservation and Reconstruction in Xinjiang

为满足"新疆生态建设和可持续发展战略研究"项目的需要,设计并编制了新疆生态保育与重建区划图。该区划图是根据新疆"三山夹两盆"的总体地势特征、"三圈九带"的生态景观特征,以及"山地-绿洲-过渡带-荒漠系统-生态范式"可持续农业范式的认识,参考新疆地貌区划、植被区划、新疆生态功能区划、新疆维吾尔自治区综合自然区划等资料,确定新疆生态保育与重建分区。该区划图充分反映了新疆大的山盆结构下三圈九带的景观生态特征,体现了新疆水平圈层结构和垂直带结构的总体特征。

Regionalization means to summarize the processes and types of comprehensive research about the formation,development,diversity,combination,and relationship of regional units.Ecological regionalization means to divides the ecological domain into regions by the principles and methods of ecology on the basis of objective understanding and sufficient study to ecosystem.Ecological regionalization indicates the comparability,dissimilarity laws and the impacts of human activities to ecosystem.To meet the needs of the ＂the study to ecological construction and sustainable development strategy in Xinjiang＂ project,the regionalization map of ecological conservation and reconstruction in Xinjiang Uygur Autonomous Region is designed and presented.In order to provide good services for the sustainable development of agriculture,forestry and animal husbandry,the intention of this project is to correctly understand the characteristics and problems of the ecological environment in Xinjiang.This paper introduces the background and mapping information on the design and preparation of the regionalization map,and analyzes the characteristics of the map.The mountain-basin system is the main geomorphologic feature in Xinjiang.The pattern of three circles and nine belts are the characteristic of ecological landscape in Xinjiang.The paradigm of ＂mountain-oasis-desert eco-productivity＂ is proposed.According to these understanding,the regionalization map is completed by taking into account climate,soil,geomorphologic regionalization,vegetation regionalization,ecological function regionalization and synthetically integrated natural regionalization in Xinjiang.Based on the principle of stratification and classification,the ecological regionalization hierarchy of Xinjiang includes four levels,i.e.,ecological domain,ecological region,ecological sub-region and ecological district.The regionalization map of ecological conservation and reconstruction was designed to be a filling color map.The regionalization map shows that the four levels of ecological regionalization is respectively presented by color,line-type,and code.The regionalization map gives full expression to the level of circle-layer structure and vertical belts structure.
