The Concept of Sustainable Development Revisited

The concept of sustainable development is here revised in the light of a brief historical analysis, followed by a semantic analysis of the expressions development and sustainability. The authors criticize the common use of this concept in a loose way or in wide generalizations, to conclude, based on the principles of human ecology, that it is only possible to make it operational in limited spans of time and in limited spatial units.     

地理系统与地理治理

 通过介绍地理科学的基础研究核心--地理系统,梳理了地理系统的组成要素：地理要素、地理空间以及人地系统,说明其独特的系统结构与系统功能。结果表明,地理系统包含了地球表层系统、土地利用系统、人类活动系统与人地耦合系统。地理科学应用研究核心是地理治理。地理治理是国家治理体系的重要组成部分,包含了调查评价、规划设计、地理模拟、地理工程、监测预警。地理治理目前在国家治理体系中的应用体现在国土空间治理方面,主要有自然资源调查、国土空间规划、国土生态修复等。中国地理科学需要创新发展理论、方法和技术体系,为全球的可持续发展做出更大贡献。
