城市人居环境的协调发展度研究——以上海市青浦区为例

城市人居环境的可持续发展体系是一个由人口、社会、资源、环境与经济5个子系统构成的开放巨系统。通过提出综合衡量系统“协调性”和“发展水平”的“协调发展度”模型，研究人居环境复合系统内5个子系统之间协调发展度情况。并运用灰色预测理论构建GM（1，N）动态模型，预测未来几年各子系统之间协调发展的状况。

GHG emission reductions and costs to achieve Kyoto target

Emission projection and marginal abatement cost curves (MACs) are the central components of any assessment of future carbonmarket, such as CDM (clean development mechanism) potentials, carbon quota price etc. However, they are products of very complex,dynamic systems driven by forces like population growth, economic development, resource endowments, technology progress and so on. The modeling approaches for emission projection and MACs evaluation were summarized, and some major models and their results were compared.Accordingly, reduction and cost requirements to achieve the Kyoto target were estimated. It is concluded that Annex I Parties‘ total reduction requirements range from 503--1304 MtC with USA participation and decrease significantly to 140--612 MtC after USA‘ s withdrawal. Total costs vary from 21--77 BUSD with USA and from 5--36 BUSD without USA if only domestic reduction actions are taken. The costs would sharply reduce while considering the three flexible mechanisms defined in the Kyoto Protocol with domestic actions‘ share in the all mitigation strategies drons to only 0--16%.

三峡大坝对重庆城区水环境的影响及对策

本文在假定城区排污量维持1990年水平的条件下,用计算机模拟了三峡大坝建成后重庆城区长江、嘉陵江岸边污染带增宽的情况。同时,借助水质模型模拟的2000年时城区的水质状况和城区两个控制断面上的多年监测浓度值,用灰色理论预测了三峡水库形成后重庆城区的实际岸边污染带宽度和九种污染物的断面平均浓度。最后,提出一套最佳的对策方案及投资估算。     

花岗岩类岩体与金矿床成因关系的探讨

花岗岩类岩体与金矿床存在着密切的空间联系，其成因关系一直是矿床学界争论的焦点，目前传统的岩浆热液成因观点仍居统治地位。随着地质资料的积累，高温高压实验技术，尤其是金矿床同位素定年技术的进展，传统观点受到了严峻挑战。成岩成矿的时代与时差、成矿流体的来源和成矿物质的来源等确定金矿床成因类型关键因素的综合研究表明，有密切空间关系的金矿床与花岗岩类岩体之间，在多数情况下两者并无直接的成因联系，金矿床不是岩浆热液成因，而是与大气降水或建造水有关的改造成矿作用的产物。     

美国《濒危物种法》介评

一般而言,对濒危物种实施法律保护是世界各国生物多样性保护法律的核心.从世界范围看,美国的濒危物种保护法律制度是极有特色和卓有成效的,其立法规定和司法实践较为完善和成熟.对其进行研究对我国的濒危物种保护立法有较大的借鉴意义.鉴于此,本文对美国濒危物种保护制度的核心--联邦《濒危物种法》（the Endange red Species Act）的主要内容进行研究,以期为我国的物种保护法制建设服务.
