In scope, the environmental policies include pollution control policies, ecological conservation policies and basic international environmental policies which should be considered based on the following aspects. （1） The urban environment issue possibly emerges in the urban inside and outside interactions, thus the government to the ecological environment must pay attention to the sector coordination, and even must global footprint from the national and criterion consideration. （2） Environmental protection is not only adapted to the needs of the environment through the transformation, but stressed that ecological construction, that is, to promote the coordination between mankind and the natural environment. Development and protection are regional which should be global and intertwined.展开更多

Despite that there is a considerable amount of scientific researches on the urban nature in urban and suburb area, the comprehensive research of URNA is still rare. After analyzing the concept and value of URNA, this paper presented a methodology for comprehensive evaluation of URNA by adopting methods of document analysis, prior-selection process, analytic hierarchy process and vector resemblance-degree. As a result, the comprehensive evaluation index of URNA includes target level A, rule level B(ecological environment value, ecological recreation value, social culture value, scientific research value), index level C( diversity,singularity,nature,area,stability,recreation,landscape element,aesthetics,history,scientific), and index level D(20 items). Each index weight of comprehensive evaluation system of URNA of Shanghai was confirmed finally.展开更多
