Jiaodong Peninsula Comprehensive Evaluation Of The Geological Environment And Land Resources Sustainable Use

Jiaodong peninsula is the biggest peninsula in the eastern of China, located in shandong province, including all of Yantai and Weihai and the most of Qingdao, which driving the economy leaping development zone, and is the core area of the construction of shandong peninsula blue economic zone. Therefore, the study on geological environment quality and the sustainable utilization of land resources in jiaodong peninsula have important and practical significance. Based on the field investigation and study, consulting a large number of relevant materials, the overall research of the jiaodong peninsula geological environment quality evaluation and the sustainable utilization of land resources is studied.The concrete content as follows:(1) on the basis of the investigation and widely collected, Jiaodong peninsula natural geographical environment and the geologic background conditions are studied, the main geological hazard and environmental geology problems of jiaodong peninsula is found out, which including earthquake disasters and regional crustal stability, ground deformation problems, slope environmental variation problem, Marine fluid disasters, water and soil environment variation problem five categories, and kinds of the main geological hazard and environmental geology characteristics and distribution problems were analyzed and studied.(2) Main geological disasters and geological environment problems of jiaodong peninsula are analyzed and studied, jiaodong peninsula geological environment quality quantitative evaluation index system is identified by 3 first-order index and 13 secondary-indexes, and using the analytic hierarchy process (AHP) to determine the weights of the 13 secondary-indexes. Then the area is divided into 659 evaluation units and using the hierarchical analysis comprehensive evaluation (AHP-FUZZY) to evaluate the geological environment quality of the each unit, obtaining the jiaodong peninsula geological environmental quality assessment figure, and analysis the evaluation results, and the suggestions of the jiaodong peninsula geological environment quality for optimum utilization is put forward.(3) Based on the data of the statistical yearbook of shandong province ,yantai, Qingdao and weihai cities are researching units, The jiaodong peninsula urban geological environment quality evaluation index system is identified by the five primary-index, 18 secondary-indexes, using multi-factor weighting method to analyze 2004~2008 dynamic change trends of geological environment quality of the three cities jiaodong peninsula.(4) For further research on geological environmental quality and economic development, and puts forward the relationship of geological environment quality and losses, analyzing the concepts of degree of 2004~2008 jiaodong peninsula three urban geological environmental quality and in GDP per unit area, it is concluded that the dynamic relationship in Qingdao, yantai and weihai city geological environment quality and losses degree of 2004~2008.(5) On the basis of the study, the evaluation model of jiaodong peninsula land resources development suitability is evaluated, and the suitability figure of the jiaodong peninsula land resources development is obatined, according to the evaluation results,the countermeasures and Suggestions of the jiaodong peninsula sustainable utilization of land resources is put forward.Research results can provide decision-making basis for creating and construction for the environmental protection and the major engineering planning and layout of the jiaodong peninsula, which has practical significance to the blue economic zone of shandong peninsula.
