The Urbanization Pattern of China in the 21st Century

The 21st century is referred to as a "century for cities"or "era for cities", and China has also speeded up its processof urbanization, which will bring massive influence to theeconomic development of the country and also to theworld. Joseph E. Stiglize, a winner of The Nobel Prize onEconomy, said that (the urbanization in China and thedevelopment of high technologies in the United Stateswill be two major subjects with a profound effect to thedevelopment of all mankind in the 21st century) …     

The Urbanization Pattern of China in the 21st Century

Abstract

This paper begins by analysing the mutual influence between international trade and the environment, and then proceeds to explore the environment and trade conflicts. On the basis of sustainable development theories and the above discussion, the article suggests taking sustainable trade as a solution to the existing conflicts. This paper aims to find the way to strike a balance between international trade and environment based on the present situation in China.     

贵州省主要地质灾害危险度区划研究

结合贵州省地理环境和地质灾害特征,选择地形地貌、工程地质岩组、断裂构造作用、河流切割程度、年均降雨量及历史地质灾害分布密度等6个一级区划指标和24个二级区划指标,采用黄金分割法确定各指标的权重;应用综合分析的因子叠加法,按4级危险度分区标准,对贵州省主要地质灾害危险度进行区划。区划结果包括:极高危险区约3.22×104km2;高危险区约0.85×104km2;中危险区约2.99×104km2;低危险区约10.56×104km2。采用离散多态系统可靠度的矩阵分析法,认为贵州主要地质灾害发生的危险性主要处在中危险区。
