Modern Urban Green Space Rationalization Study

21st century, Along with the world urbanization advancement speeding up, The city is receiving such unbalanced ecology puzzles as the air pollution, the acid rain, the water resources day by day drying up and so on. Accelerating city ecology construction has become the only way for sustainable development of the cities in our country. At the same time, the modern city green space construction has come from the watching -and-amusement stage to the dual goal stage of building and improving the urban environment and satisfying the landscape effect. Traditional development plan of urban green space already can not suit the demand of new urban development . The modern urban green space system plan of the fusion of ecology and the corresponding interdisciplinary studies is emerging from the different stratification plane. This determined topic research content is precisely based on understanding vital realistic question of the urban green space system plan work . The article embarks from the idea, Carries on the elaboration to the three big aspects of the city green space system plan rationalization, introduces landscape ecology knowledge to carry on the ecology green space plan of the scientific layout —scientificly utilize the advanced technich to guide the plan —scientificly to establish appraisal target system to guarantee the benign development of the plan process. This article is composed by four parts: 1st, concept limits; 2nd, the construction of landscape of urban green land system plan; 3rd, the utilization of 3S technology in urban green space system; 4th, appraisal target system establishment in urban green space system. 5th, conclusion . 1st, elaborate separately to the concept of "rationality" and "green space system", And carry on the analysis to the relations of green space system and the overall plan; Take time as clue to introduce the theory development course of green space system, And carry on the appraisal to the present green space system to elaborate its development tendency. 2nd, introduce the landscape of urban green land system according to the landscape ecology basic principle, carry on the elaboration from the principle and the direction which constructs. Carry on the analysis to the construction of the urban green space landscape system from two aspects about the landscape ecology and the landscape style. Carry on the elaboration Unifying the green space system plan of the Suzhou industry garden area. 3rd, elaborate the 3S technology constitution and its system utilization in the city green space. From the city green space resources investigation, the city ecological environment monitor, the green quantity estimation and the city green space landscape pattern, analyze four aspects to carry on the elaboration. 4th, introduce from the importance of appraisal target system of city green space system, Has summarized the domestic and foreign green spaces system appraisal target development condition. And establish the principle and the level of the city green space landscape target system, Make every effort to establish a set of practical appraisal targets which are science and reasonable. 5 th, Summing up the systematic theory of urban green land goes through and"has no stage of planning"to rise and develop to the trilogy at "rational stage"until"perceptual stage".The scientific trend is appearing day by day in the green land system。Point out at the same time the article is studied with the development of discipline about the systematic reason of urban green land, should go on a deep one rich in content studying.
