【摘要】：陕北黄土丘陵沟壑区群聚着我国重要的能化产业，水土流失和风沙危害在我省最严重，生态环境极其脆弱，生态环境保护与基地建设的矛盾越来越越突出。随着能源开发，环境负荷不断增加，生态退化和环境污染问题已成为制约能源开采得主要矛盾。同时，从微观角度看，以吴起县为例的石油产业占主导的地区经济虽然一定程度发展，城乡二元结构矛盾却日益凸显，粗放型经济增长方式亟待改变。本研究从能化产业集群建设对生态环境影响和县域经济结构失衡这两大问题入手，，以延安市吴起县为研究对象，探讨了在陕北能源化工产业结构调整宏观背景下，如何利用GIS技术进行能源化工工业园空间优化配置的方法。依托《吴起县土地利用总体规划》、《吴起县国民经济和社会发展第十二个五年规划纲要》、《吴起县乡镇企业工业园区规划》、《吴起县能源化工园区总体规划》等相关规划要求，以吴起县2009年土地利用现状调查及10、11、12三年的土地利用现状变更调查数据库为基础，结合实地调研情况，综合考虑重点建设项目用地规划要求、县域资源禀赋和社会经济条件，将坡度与地形因素、水资源、交通网络辐射影响、人口因素与原材料因素作为评价指标，建立能源化工业园重点项目建设备选区适宜性评价指标体系。并利用3s技术、叠置分析、缓冲区分析、制图统计等功能量化标准化各评价指标分值，利用层次综合评价法确定各评价指标权重，求得综合评价值，筛选出适宜建设能化工园区的目标区域。并根据产业布局情况和吴起县实地调研分析评价结果的合理性，验证空间优化配置方案的正确性。
[Abstract]:In the loess hilly and gully region of northern Shaanxi, there are important energy and chemical industries in our country. Soil erosion and wind and sand damage are the most serious in our province, the ecological environment is extremely fragile, and the contradiction between ecological environment protection and base construction is more and more prominent. With the development of energy and the increasing of environmental load, ecological degradation and environmental pollution have become the main contradiction restricting energy exploitation. At the same time, taking Wuqi County as an example, the regional economy dominated by petroleum industry has developed to a certain extent, but the contradiction of urban-rural dual structure has become increasingly prominent, and the extensive economic growth mode needs to be changed urgently. This study starts with the impact of energy and chemical industry cluster construction on ecological environment and the imbalance of county economic structure, takes Wuqi County of Yan'an City as the research object, and discusses the macro-background of energy and chemical industry structure adjustment in Northern Shaanxi. How to make use of GIS technology to optimize space allocation of energy and chemical industry park. Relying on the relevant planning requirements such as the General Land use Plan of Wuqi County, the outline of the 12th Five-Year Plan for National Economic and Social Development of Wuqi County, the Planning of Wuqi County Township and Township Enterprise Industrial Park, and the General Plan of Wuqi County Energy and Chemical Industry Park, etc. Based on the survey of land use status in Wuqi County in 2009 and the land use status change survey database of 101112 years in Wuqi County, combined with the field investigation, the requirements of land use planning for key construction projects, the resource endowment and social and economic conditions in the county area are comprehensively considered. Taking slope and topographic factors, water resources, radiation effect of traffic network, population factors and raw materials as evaluation indexes, the suitability evaluation index system of key projects in energy industry park is established. Using 3s technology, overlay analysis, buffer analysis, cartographic statistics and other functions to quantify and standardize the evaluation index scores, using the hierarchical comprehensive evaluation method to determine the weight of each evaluation index, and to obtain the comprehensive evaluation value. The target area suitable for the construction of energy chemical industry park was screened out. According to the situation of industrial layout and Wuqi County field investigation and analysis of the rationality of the evaluation results to verify the correctness of spatial optimal allocation.
