Based on characteristics of ecologic environment and ecologic economy, energy resource use in the Manas River Basin of Xinjiang Wei Autonomous Region is calculated using the energy method. The calculation shows that the energy self-sufficiency ratio is 98.06%,and the renewable resource energy ratio,65%,which indicate that mountain and desert are the main ecologic conditions to support the development of ecological economy.
By using the Analytic Hierarchy Process,from 7 respects of synthesized economic strength,open degree,industry's benefit,infrastructure,city size,scientific and technological educational level,state of ecological environment,including 19 indexes altogether,the author carries on comprehensive appraisal analysis to 17 prefecture-level cities in Anhui Province,and comparative analysis on singular index competitiveness and comprehensive competitiveness to each city,then promotes some suggestions to improve the urban competitiveness
The results showthat:the ecological footprint per cap is 1.552 831hm2,the ecological capacity per cap is 0.278 329hm2,and the ecological deficit is 1.274 502hm2.From the analyses above,it can be seen that the demands of human consumption exceed the capacity of natural ecosystem and ecological environment is deteriorating at a rapid pace.
Circum-economy is the economy pattern that regards mankind sustainable development as objective and circum-use of resources and environment protection as substance base,which highly harmonizes manufacturer,consumer and decomposer.

The great development of the construction of country towns has been obtai- ned since liberation, but some economical and technical shortcomings and inper- fections exist in the construction and planning of county towns. some important questions presented by the experience of the construction and planning of coun- ty towns were discussed in the present paper. They are: the determination of the projects of industry construction, the estimation of the scale of the countny towns, the reasonable organization of the communication and transport, the united ma- nagement of the housing projects and the improvement of the environment.
The theme of the thesis is that the nuclear part of the ecological viewpointconcerns the organical unity of environment and the organical unity of man andenvironment.Thus it becomes the governing principle of environmental science,causing the subject form of environmental science to developt oward the directionof unity.At the same time,the ecological viewpoint changes from the principleof ecological equilibrium to the principle of ecological evolution.
This paper consists of four parts, 1 .the characteristics of the county-town system, 2. the main factors which influence the county-town system, 3.the method of dividing the county-town orders, and 4.conclusions.The county-town being their center, all towns in a county region comprise an integrated town system or network, which may be divided into four orders, that is, (1) county center; (2)the local centres of some neighbourhood communes; (3) commune towns5 and (4) the small towns within a commune. Here, the...
This paper consists of four parts, 1 .the characteristics of the county-town system, 2. the main factors which influence the county-town system, 3.the method of dividing the county-town orders, and 4.conclusions.The county-town being their center, all towns in a county region comprise an integrated town system or network, which may be divided into four orders, that is, (1) county center; (2)the local centres of some neighbourhood communes; (3) commune towns5 and (4) the small towns within a commune. Here, the dividing method is chiefly based upon the service regions determined by aggregate amounts of sales, if we chooce certain kinds of goods.Generally speaking, the service region of the first or third class towns is mainly limited by administrative function.In other words, it is common that their service region roughly coincides with the limits of administrative jurisdiction in which they exist.On the other hand, the service region of the second or fourth class towns, which cash off the administrative control to a great extent, is much more influenced by their economic functions and some other factors, such as location, physical environment and social or human factors, etc, which have influence on their origins and growth.
