青海省海西州区域用地集约利用评价研究

Evaluation of Intensive Land Use of State Haixi in Qinghai Province

工业化、城镇化速度的加快,导致各种建设用地增加,使我国土地供需矛盾加剧。随着集约节约用地政策的提出,土地集约利用评价随之在各地开展。为促进西部地区经济发展与土地利用的相互协调,以青海省海西州为例,结合西部地区特点及发展情况,以2003—2008年青海省海西州土地利用变更数据和青海省统计年鉴等资料为基础,以《建设用地节约集约利用评价规程》为依据,建立评价指标体系,以特尔菲法确定指标权重,用极值标准化法对指标进行标准化处理,计算各级评价指数分值和总指数分值,对海西州区域土地集约利用程度进行评价。结果表明,利用强度指数(UII)逐年增长,用地弹性指数(EI)逐年下降,增长耗地指数(GCI)平稳波动,总指数波动增长。海西地区经济发展与建设用地利用不协调,需要政策引导,加大土地管理力度。

The acceleration of industrialization and urbanization leads to increase of construction land areas and makes China＇s land supply and demand conflict.As the policy about using land economical and intensive proposed,the evaluation of intensive land use followed to carry out in various regions to promote the economic development in the western region and coordination of land use.According to land for construction of economical and intensive use of evaluation procedures,the regional intensive land use was evaluated with the combination of the characteristics and the development of the western region.The study area was State Haixi in Qinghai Province.The land use change data were adopted from State Haixi and Statistical Yearbook of Qinghai Province based on the 2003—2008 period,etc.The evaluation index system was established and Delphi method was used to determine the index weight,then the indexes was standardized by the extreme standardized method and all levels of evaluation index score and the total index score was calculated.Results showed that UII was growing year by year And EI was declining,GCI was fluctuating smoothly.The general index was fluctuation in growth.The economic development and the use of construction land in Haixi were inconsistent.The study area need guidance by policy and increase land management efforts.
