摘 要:地理国情普查及监测获取了大量的地表自然和人文地理要素数据,为自然资源分析提供了重要数据源,数据挖掘分析是地理国情监测深化社会服务功能的重要发展方向。本文以广东省地理国情监测数据为基础,结合人口、土地、矿产等专题数据,分析广东省各县(区)山、水、林、田、湖、草、海等自然资源要素特征,再从自然资源总量、利用程度和开发潜力3个方面构建自然省情评价指标体系,最后通过自下而上分层设定权重方式获得以县(区)为单元的广东省自然省情指数分布。结果表明,自然资源综合禀赋水平较高的区域主要分布在粤北地区和粤西地区;受区域自然资源消耗与人类活动高强度干扰,珠三角区域综合水平普遍较低;部分沿海县(区)因拥有丰富的海岸线资源而呈现较高水平。自然省情分析有助于感知国土空间状态,为国土空间规划科学决策提供相关依据。Geographical national conditions survey and monitoring has obtained a large number of data on surface natural and human geography,which is an important data source for analyzing natural resources.Data analysis and mining is an important trend for deepening social service functions in geography monitoring project.Firstly,the article analyzes the characteristics of natural resources elements,such as mountains,water,forests,fields,lakes,grasslands and sea in counties based on the data of geography national conditions monitoring in Guangdong province combined with the thematic data of population,land and minerals.Secondly,the evaluation index system of natural resources is constructed from the three aspects of the total amount of natural resources,the degree of utilization of natural resources and the potential development of natural resources.Finally,the index distribution of natural conditions of Guangdong province with counties(districts)as the unit is obtained by means of setting weights from the analytic hierarchy process.The results show that the areas with higher natural resources comprehensive endowment are mainly distributed in the northern part of Guangdong and western part of Guangdong.The comprehensive level of the Pearl River Delta region is generally low due to the high intensity of regional natural resources consumption and human activities;some coastal counties also show a high level because of the abundant coastline resources.The analysis of natural and provincial conditions is helpful to perceive the state of the land space and provides relevant evidence for the scientific decision-making of land space planning.
