Research on the optimal construction scale for rural Safe Drinking Water projects in Qingdao Based on GA and GIS

摘要

In order to determine the reasonable construction scales of the water supply projects in rural areas, in this paper, we firstly analyzed the major influencing factors to safe water supply projects construction scale. Secondly we respectively establish correlation equations between scales and water works construction cost, pipeline network cost and running cost. Further, with the correlation equations we propose an optimal model for projects construction scale and suggest a water supply projects construction scale's optimization analysis methods in rural area based on GIS & GA. Finally the model and methods are used in Jiaonan rural area in Qingdao, and obtained the optimal solution also the economic reasonable water supply projects scale of this rural area.
