长江源头的小流域综合治理及其效能

孟宗沟小流域是长江源头高寒牧区水土流失综合治理试点。通过沟道与坡面两方面的治理，工程措施与生物措施相结合，增加地面、坡面植被，栏蓄径流，减少泥沙下泄，在防护效能上取得了显著成果。     

对产生环境问题的根源探析

从多维、多学科的视角，就环境问题产生的原因进行了比较系统，全面的研究和探讨。具体包括环境问题产生的哲学根源、宗教根源、伦理根源、技术根源和经济根源。从表面上看，环境问题是一个技术问题、经济问题；但从深层次考察，环境问题则也是哲学问题、宗教问题和伦理问题。环境问题的根本解决，不仅有赖于技术进步和经济法律制度的变革，更有赖于人类文明的转型和伦理观念的觉悟。

Spatial distribution of ecological security status assessment of West-Liaohe River based on geographic information system

Eco-security assessment is a hot research area in resource and environmental science, which involves data with much spatial, non-linear, and random features. Geographic information system (GIS), as a useful tool to analyze and manage spatial information, has a superior advantage in this field. A case study in the western part of the Liaohe River featuring a method of eco-security spatial differences (ESSD) based on GIS is developed in this paper. The method includes four steps: 1) developing the pressure-state-response (P-S-R) framework with site data; 2) digitizing West-Liaohe River and setting its GRID database of ecosecurity assessment indicators; 3) figuring out the relative membership degree (RMD) of eco-security indicators by using the analytical hierarchy process with the weight of indicator; 4) classifying the security zone and mapping the assessment result of eco-security status in grid by GIS method of assigning and clustering. The visual spatial differences of eco-security based on GIS enables decision makers to know the status of eco-security better in making policies for achieving sustainability. __________ Translated from Environmental Science, 2005, 26(5): 28–33 [译自: 环境科学]     

危险化学品活性反应危害及混配危险的规则研究（X）

卤素指周期表中第ⅦA族元素。由于卤素单质具有很高的化学活泼性，常常与活泼金属形成离子型盐，其中卤素是-1价阴离子。除氟外，卤素均显正氧化态（＋1，＋3，＋5，＋7），其化合物的键是极性共价键，其中最典型的是氯、溴、碘的含氧化合物和卤问化合物。在含氧化合物中常包含卤素与氧原子问的双键。     

城市水业私有化问题分析及研究

私人投资水业在今后一定时间内是解决城市基础设施建设的主要手段之一.它能够解决城市基础设施投资资金短缺的问题;实现基础设施行业投资结构多元化,促进体制改革;引入竞争机制,提高服务质量;引入先进技术与科学的管理手段,提高经营管理效率.本文首先介绍了私有化的概念,进而指出城市水业的私有化并不是解除政府保障基本水服务的职责,而是完成运营者到监管者的转变,最后以典型案例分析了私人投资水业存在着巨大的机会和风险.
