地缘环境定量研究综述

Review of Quantitative Study on Geo-environment

地缘环境分析是明晰地缘环境、辅助国家战略决策的重要手段,而地缘环境定量研究是提高地缘环境分析结果科学性、准确性的主要途径。该文重点对国内外地缘环境定量研究进行总结归纳,从地缘要素作用机理研究、地缘位势与地缘影响力测度、地缘关系测度、地缘格局划分、地缘环境安全评价、地缘环境模拟与预测等领域综述和评价了地缘环境定量研究的理论、方法和技术研究现状,指出了地缘环境定量研究面临的机遇和挑战。近年来随着相关方法和技术的应用,地缘环境定量研究已经取得积极进展,但仍然存在许多问题有待解决:1)基础理论研究需要进一步加强;2)技术手段需要进一步交叉融合;3)研究方法需要进一步验证;4)研究领域和研究区域需要进一步拓展。研究结果对推动地缘学科的发展具有一定的参考价值。

Geo-environment analysis is a key means making geo-environment clear and aiding state strategy decision,and quantitative study is the main method improving the scientificity and accuracy of geo-environment analysis.In recent years,with the application of relevant methods and technologies,quantitative research on geo-environment has achieved some development.Current theories,methods and technologies of quantitative research on geo-environment were analyzed and assessed from some perspectives,including the study of action mechanism about geo-environment factors,the measure of geo-potential and geopolitics influence,the measure of geo-relationship,the division of geo-pattern,the safety evaluation of geo-environment,the simulation and prediction of geo-environment.Then the challenges of quantitative research on geo-environment were put forward.The results show that important progress has been made in quantitative research on geo-environment,but there exist many problems.First,up to now,the basic theory and method system of geosciences has not been established,which should be strengthened.Second,interdisciplinary methods and technologies should be further introduced into geo-environment research.Third,current methods and models need to be verified,which is especially important for forecasting methods.Last,research fields and regions need to be further expanded.The results are valuable to promote further development of geo-environment research.
