Eco-industrial parks: national pilot practices in China

China has rapidly developed a number of Eco-industrial parks (EIPs) in recent years. In order to promote and regulate their development, two government agencies, the Ministry of Environmental Protection and the National Development and Reform Commission are currently engaged in promoting national pilot EIP programs. Both agencies have developed their own management systems, and 60 industrial parks have been approved for construction of national pilot EIPs, among which six parks appear in both lists of the two agencies. This article introduces the practice of the national pilot EIPs. It first describes the management systems and achievements within the two programs, and then summarizes the problems encountered thus far in program implementation. Finally it proposes brief suggestions for future development of EIPs.     

农业现代化、信息化与农业面源污染研究

利用2003年-2013年中国30个省份的面板数据,检验了农业现代化、信息化与农业面源污染之间的关系.研究发现,农业现代化对农业面源污染有着一定的加重作用;信息化能够有效缓解因农业现代化所导致的农业面源污染,这一现象在粮食主产省同样存在,说明信息化能够发挥减污增绿的作用;农业环境库兹涅茨曲线(EKC)也得到验证.因此,应进一步推进信息化发展,有效利用信息化对农业现代化所致农业面源污染的缓解作用,还应多措并举促进农民增收,加快农民收入越过EKC曲线拐点.     

粘性泥石流一维运动数学模型

粘性泥石流是指自然界中最典型的一种泥石流。作者依据野外原型观测和室内实验，证实该类流体具有带流核的层流特征并可用宾汉（Ｂｉｎｇｈａｍ）模型来表达。在此基础上推导其阻力和平均流速计算方法。我们认为，粘性泥石流作为不可压缩连续介质流体，符合质量、动量守恒律，因此可采用纳维－斯托克斯方程组来表达。考虑到它为拟线性双曲型偏微分方程组和阻力参数等特点，应用Ｌａｘ－Ｆｒｉｅｄｒｉｃｈｓ差分格式，选用云南东川蒋家沟的原型观测资料作为边、初值条件，编制计算机程序及数据库，而获得粘性泥石流水深、流速等要素的时空变化规律。该模型可以直接用于泥石流工程防治和量化的预测和警报     

4阶导数光谱法同时测定酚类及芳胺的统计性检验

介绍４阶导数光谱法同时测定污水中酚类及芳胺方法的统计性检验，通过样品加标回收实验以及Ｆ检验和ｔ检验证明该方法的精密度和准确度均优于国家环保局推荐的４－氨基安替比林先度法删酚和萘乙二胺偶氮光度法测芳胺的实验方法。     

金矿渣场废水对地面水环境的影响评价

阐述了在降雨时金矿渣场浸渣中残留的氰化物及泥沙淋溶于雨水中,形成地表径流进入地面水,对地面水环境造成的污染影响。具体介绍了在降雨时,渣场地表径流量、径流中污染物排放量、地面水（湖泊）允许纳污量的预测模式的应用。可为一般工矿企业露天渣场废水预测及环境影响评价提供借鉴。     

Environmental performance rating and disclosure: China's Green Watch program

In this paper we describe a new incentive-based pollution control program in China, in which the environmental performance of firms is rated from best to worst using five colors--green, blue, yellow, red and black--and the ratings are disseminated to the public through the media. We focus on the first two municipal disclosure programs, which have been implemented at very different levels of economic and institutional development. In both cases, the increases in compliance with pollution regulations have been similar to increases produced by public disclosure programs in Indonesia, the Philippines, and Vietnam. The results suggest that incentives created by public disclosure may significantly reduce pollution in China, even though environmental NGO's play little role and there is no formal channel for public participation in environmental regulation.
