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。     

台湾的环境与生态危机及解决思路--从石门水库淤积事件谈起

石门水库在桃园县，桃园县位于台湾省西北部，西北临台湾海峡，东北邻台北县，西南与新竹县、东南与宜兰县交界。全县面积1220平方千米。人口约135万。过去县内遍植桃树，开花时缤纷馨郁，全县如一个大花园。有“桃仔园”之称，后来设县正名为桃园。全县地形分为滨海平原、丘陵台地和高山地形三大部分，是台湾主要水稻产区之一，产量居全省第四位。
