Taiyuan City Residential Area Green Space Water-saving Decision-making Method Research

With the speeding up of urbanization in our country, the environment problem had been becomed more and more serious, the water shortage problem is One of the particularly prominents, the construction of water-saving green space is the only way to realize the sustainable development and now, the construction of water-saving landscape contains Water plants to choose,Water-saving technology and managements,Rainwater utilization and landscape, Water-saving landscape design strategy and so on. Different researchers from different angles on water saving put forward some measures and Suggestions. But different advices on how to combined with the actual conditions, and how to meet the demand of users on the basis of realizing the organic combination of different kinds of water-saving measures, so it Is still an open question.This study's target is to establish a set of residential green space water-saving decision method,and to help users finding their own goal of water saving measures. Research by establishing residential green space pattern, analysis of residential green space saving water way, building a database of plant drought resistance and ornamental value, On the basis of plant irrigation demand, rainwater use of investment demand and green space landscape effect, Residential green space water-saving decision-making model will be established. On this basis, through analysis of typical cases and to test the decision model is obtained. The results of the study are as follows:(1) Establishing of taiyuan city residential area green space pattern and model(2) The evaluation of plant drought resistance of common garden plant of taiyuan, making an evaluation of the different configuration mode of ornamental value, and getting the green land irrigation demand different configuration mode.(3) According to the residential area of rain of engineering technology, and determining the rainwater collection project construction investment and operation costs.(4) Establishing taiyuan city rainwater collection using technology, According to the economic situation of taiyuan city and has been clear about the equipment investment of the scheme.(5) On the basis of plant irrigation demand, rainwater use of investment demand and green space landscape effect, Residential green space water-saving decision-making model will be established.(6) Using cases to test decision model, and Decision-making provides a good technical support for the user.
