Actively Dealing with Climate Change and Striving to Strengthen the Capability of Sustainable Development

Either from the perspective of the finite supply capacity of global resources and energy,or from the perspective of global environment restrictive conditions,developing countries can not repeat the old development road of developed countries,either in view of the international pressure China is currently facing,or in view of China’s own resources endowment and stages of development,we must actively face such a challenge of climate change.We must recognize that the issue of climate change may be a great restraint to the present and future eco-social development,and may also be an important driving force and new opportunity to push forward the transformation of development pattern,to take a new road of industrialization and to realize sustainable development.This demands us,on the one hand,to take the Scientific Outlook of Development as the guide to make efforts to control the emission of greenhouse gases and continuously increase the capability of adapting to climatic change,and set up the overall plan to respond to climate change of our country,and on the other hand,we should unswervingly take the road of sustainable development,save energy,optimize energy structure and strengthen biological protection in slowing and adapting to climate change.     

可持续发展环境约束条件下的水资源最优配置及实证研究

在相关理论分析和Weber模型的基础上。拓展建立了面向水资源可持续发展的水资源最优配置模型。引入了基于政府管制的影响作用、沿河流域的水用户的实际消耗水量、实际排放水量、河流中可供使用水量及所排放污水水质水平等5个变量函数．通过政府管制下的水质和水量的河道内流量需求等环境约束条件．确保水资源利用始终满足最小基流水量。通过求量优解，计算得出在环境约束下达到最优配置时各个变量函数与对下游地区外部性之间的相关性。接着。本文对陕北黄土高原沿Y河的35家企业进行了实际调查．收集了2个年度共8个季度的观测值，应用计量经济Pand Data模型。对35个节点、8个季度的共280个数据作为混合样本进行经济计量分析。验证了相关结论。最后。还提出一些制定环境约束条件以及水用户间建立水资源环境生态补偿金机制等政策建议。     

基于高程的环境库兹涅茨曲线实证分析

本文利用GIS的空间分析技术。以高程带为取样单元。研究在高程带上三种主要的大气污染物与经济发展之间的定量关系。以重庆市为例,验证环境库兹涅茨在高程上是否存在。研究结果发现。污染物浓度随高程的增加呈非单调下降的趋势。人均GDP随高程的增加先增大后减小。在高程上。污染物浓度与经济发展之间的关系和两者在时间序列和国别（或地区）序列上环境库兹涅茨曲线研究的结论相似。其中。TSP和NOx分别与人均GDP之间呈较稳定的呈“N”形和饲“U”形关系。受人口密度和高程影响较大；而SO2与人均GDP之间关系不稳定。     

环境安全：21世纪人类面临的根本问题

本文从人类社会的可持续进步和国家的可持续发展两个层面,深层次地分析了环境安全问题的不可替代的重要性,并从理论和实践两个方面得出：第一,我国应将环境安全的保证能力作为综合国力的重要组成部分;第二,应将环境安全观作为指导我国21世纪两大战略-加入WTO和西部大开发的重要方针。     

矿产资源规划理论的形成和发展

矿产资源规划是区域发展规划的重要组成部分,是政府对矿业经济进行宏观调控的一种手段。本文从理论更新和完善的角度重新确立了区域矿产资源规划的理论体系,提出矿产资源规划理论经历形成、发展与创新三个阶段,并就矿产资源配置与价格规律、矿产资源经济区划理论和可持续发展理论在其中的深远影响进行了初步探讨。     

长江流域水环境的主要问题,原因及对策探讨

从几个触目惊心的实例出发，分析出长江流域水环境存在的主要问题是水污染、泥沙淤积、对洪涝的环境容量不高和未能充分发挥水环境的多功能特别是生态功能的作用。其原因主要是工业、农业、城市和流动源排污，土壤侵蚀和人类活动不遵守持续发展原则，管理不善。作者在本文末尾提出了对策。     

Study on the Balance of Agricultural Water and Land Resources on Ningxia Plain

The article puts forward the process and means of regional water and land balance research, and then from two scenarios which are the balances under natural regulation and human intervention, calculated and analysed the balance between water and land on Ningxia Plain. For the balance under natural regulation named farmland water balance, using farmland water resource balance equation, the research estimated the monthly farmland＂ water balance of 8 major crops for all of the 12 counties on Ningxia Plain in the period of 1960-2001; for the balance under human intervention, the research estimated land-use water balance equation of the counties in 2000, and calculated the balance between land use and water resources including irrigating water of all the 12 counties on Ningxia Plain. Results showed that ①precipitation can not meet the water demand of the crops for growth and development on Ningxia Plain, and water shortage is the primary character of farmland water balance under natural regulation. ②the diversity of water and land balance of different counties is distinctly influenced by the crop structure, water quantity for irrigation and irrigation level. ③Irrigation water could meet the crop water demand on Ningxia Plain in 2000, but there was not much space to expand irrigating cultivated land.
