摘要
全球化背景下,各国社会发展迅速,如何提高用水效率、改善生态环境成为一项挑战。本文研究生产-生活-生态功能区用水效率的时空变化,有助于改善生态环境,实现可持续发展。本文采用数据包络分析法(DEA)选取评价指标。利用标准差椭圆(SDE)对空间方向分布进行分析。选择 BP 神经网络模型探讨了空间方向分布的趋势。结果表明(1) 水资源生态结构存在 "存量-流量 "联系。(2) 生产-生活-生态函数的总体水效率表明供大于求。主要形式是生态功能与生产功能之间的交换。(3) 预测结果表明,用水量从东北向西南递减,用水效率从东北向西南递增。生产函数占用了大量用水。本文建立了用水效率的生态结构理论框架,挖掘了生产-生活-生态功能与用水效率的复杂关系和变化特征。为全球水资源的可持续发展提供了新的视角。
Study on the measurement and prediction of the ecological structure for water efficiency in China: from the perspective of “production-living-ecological” function
Countries are experiencing rapid social development under globalization, and it is a challenge to increase water efficiency and improve the ecological environment. This paper investigates the spatial and temporal changes of water efficiency in production-living-ecological function, which can help to improve the ecological environment and realize sustainable development. In this paper, Data Envelopment Analysis (DEA) is used to select evaluation indicators. The spatial directional distribution was analyzed using Standard Deviation Ellipse (SDE). The trend of spatial directional distribution was explored by choosing BP neural network model. The results show that: (1) There is a “stock-flow” link in the ecological structure of water resources. (2) The overall water efficiency of the production-living-ecological function indicates an oversupply. The main form is the exchange between ecological and production function. (3) Projections show that water used decreases from northeast to southwest and water efficiency increases from northeast to southwest. The production function occupies a large amount of water use. This paper establishes the theoretical framework of ecological structure of water efficiency and excavates the complex relationship and changing characteristics of production-life-ecological function and water efficiency. It provides a new perspective for the sustainable development of global water resources.
期刊介绍:
Environment, Development and Sustainability is an international and multidisciplinary journal covering all aspects of the environmental impacts of socio-economic development. It is also concerned with the complex interactions which occur between development and environment, and its purpose is to seek ways and means for achieving sustainability in all human activities aimed at such development. The subject matter of the journal includes the following and related issues:
-mutual interactions among society, development and environment, and their implications for sustainable development
-technical, economic, ethical and philosophical aspects of sustainable development
-global sustainability - the obstacles and ways in which they could be overcome
-local and regional sustainability initiatives, their practical implementation, and relevance for use in a wider context
-development and application of indicators of sustainability
-development, verification, implementation and monitoring of policies for sustainable development
-sustainable use of land, water, energy and biological resources in development
-impacts of agriculture and forestry activities on soil and aquatic ecosystems and biodiversity
-effects of energy use and global climate change on development and sustainability
-impacts of population growth and human activities on food and other essential resources for development
-role of national and international agencies, and of international aid and trade arrangements in sustainable development
-social and cultural contexts of sustainable development
-role of education and public awareness in sustainable development
-role of political and economic instruments in sustainable development
-shortcomings of sustainable development and its alternatives.
