Low-carbon eco- city planning is especially important for China as it is in a state of rapid economic growth, urbanization acceleration, carbon emissions increase, ecological environment deterioration and intensifying economic transformation. During the process of low-carbon eco-city planning, we must consider the whole range of temporal and spatial distribution of the city and grasp the overall coordination system of time and space. We should regard it as a system of the entire biosphere and regulate urban according to true features of ecosystems, that is in a basically a three-dimensional, integrative compound patterns. We need consider the natural ecological system factors, technological physics factors, economic assets factors, social and cultural factors as well as various humanitarian factors among the urban system structure; consider the impact of the internal and external urban environmental systems; make them interact and influence each other and restrict each other through the planning of the urban system material flow, energy flow, information flow and capital flow; insists the evaluation basic of the healthy development of urbanization and the of exercise macro -control on the dynamic representation" of the city development, the "qualityrepresentatiou" ofthecity' s connotation and the air representation" of the city state in order to overcome the " urban disease " by development, to reduce the " urban disease " by planning, to treat the " urban disease " by management. Only by bringing the design and control into the scope of long-term planning and governing can we effectively monitor and guide the development and construction of low-carbon eco- towns.展开更多

By the 1970s, the water quality of Huaihe River was deteriorating daily and more than a hundred serious pollution accidents of water quality happened and caused the inestimable losses in the production, life and health of residents along the river and terribly damaged the ecological system of the river. Through the continuous large-scale treatment for more than 10 years, the deterioration of water quality in Huaihe River has been basically inhibited. Nevertheless, the water pollution in Huaihe River is, on the whole, still very serious for many reasons, including special climatic conditions, terrible lack of water resource, obsolete industrial structure and unsound management system for the river, etc. This essay deeply analyzes the rea- sons why the water pollution of Huaihe River is "chronic" and puts forward the corresponding countermeasures for how to continuously improve the water quality of the river. In the end, this essay argues that it still takes 30-50 years or even a longer period, even if every measures are implemented smoothly and strictly, to actually make the water of Huaihe River clean and gradually restore its normal ecological and environmental functions.展开更多

Much of the neoclassical thought and analysis was based on this assumption until recently. The dynamic rise in population due to rapid industrialisation and urbanization has caused the realisation that ecosystem services are also limited. Environmental degradation is a common term used to describe the loss or impairment of ecosystem services. Migration is often a consequence of environ- mental degradation; when ecosystem services are impaired and survival comes at stake. But is the degradation of essential ecosystem services sufficient to motivate people to relocate? Through a review of literature on migration and environmental degradation, this paper strives to answer the above question along with exploring ways how monitoring the deterioration of the environment on time can spare human inhabitants of any ecosystem the pains of migration in search of better means of survival and sustenance.展开更多
