为了解大口子水库水质的污染状况及污染趋势,淮安市环境监测中心站于“九五”期间对大口子水库进行了生物分析指标的监测和生物学评价。结果表明,“九五”期间,大口子水库的水质呈典型富营养化状态,且营养化程度有加重趋势;底栖动物群落的调查结果显示,化学毒性污染稍有好转,有机物污染占主导地位。提出,该水域不宜继续作为养殖基地进行水产养殖,对其污染的治理已刻不容缓。 相似文献

Industrial sustainability in China: practice and prospects for eco-industrial development 总被引:1,自引:0,他引:1
China is a large densely populated country undergoing rapid industrialization and is becoming one of the world's biggest consumers of natural resources. This circumstance provides a sharp contrast with other countries. As China is so significant in the global economy, studies of its eco-industrial development are very important. In this study we examined the state of eco-industrial development in China and have drawn conclusions from this analysis about some of the future prospects for sustainable development. In the analysis, we investigated the application of industrial ecology concepts by reference to several case studies. We have therefore described the current environmental situation in China, and have provided an overview of eco-industrial development and its implementation. Constraints to industrial sustainability in China have also been examined. We consider that eco-industrial development in China is in its infancy, and that closed loops involving chains and industrial symbiotic webs are the technological key and core of successful initiatives in the application of industrial ecology. In the case studies, we found that each system has different characteristics and management concerns. Our major conclusion is that even though China's Agenda 21 highlights the principles and sets the directions for eco-industrial development, these have not yet become essential ingredients in the country's industrial policy and practice for implementing Agenda 21. 相似文献

ICCLP: An Inexact Chance-Constrained Linear Programming Model for Land-Use Management of Lake Areas in Urban Fringes 总被引:3,自引:1,他引:2
Lake areas in urban fringes are under increasing urbanization pressure. Consequently, the conflict between rapid urban development
and the maintenance of water bodies in such areas urgently needs to be addressed. An inexact chance-constrained linear programming
(ICCLP) model for optimal land-use management of lake areas in urban fringes was developed. The ICCLP model was based on land-use
suitability assessment and land evaluation. The maximum net economic benefit (NEB) was selected as the objective of land-use
allocation. The total environmental capacity (TEC) of water systems and the public financial investment (PFI) at different
probability levels were considered key constraints. Other constraints included in the model were land-use suitability, governmental
requirements on the ratios of various land-use types, and technical constraints. A case study implementing the system was
performed for the lake area of Hanyang at the urban fringe of Wuhan, central China, based on our previous study on land-use
suitability assessment. The Hanyang lake area is under significant urbanization pressure. A 15-year optimal model for land-use
allocation is proposed during 2006 to 2020 to better protect the water system and to gain the maximum benefits of development.
Sixteen constraints were set for the optimal model. The model results indicated that NEB was between $1.48 × 109 and $8.76 × 109 or between $3.98 × 109 and $16.7 × 109, depending on the different urban-expansion patterns and land demands. The changes in total developed area and the land-use
structure were analyzed under different probabilities (q
i
) of TEC. Changes in q
i
resulted in different urban expansion patterns and demands on land, which were the direct result of the constraints imposed
by TEC and PFI. The ICCLP model might help local authorities better understand and address complex land-use systems and develop
optimal land-use management strategies that better balance urban expansion and grassland conservation. 相似文献
