城市化进程中水土资源系统耦合配置研究

在当前城市水土资源供需矛盾日趋尖锐的背景下,开展水土资源系统耦合研究,可使区域内系统水资源和土地资源利用实现优化配置。通过建立水土资源系统耦合配置模型,并运用遗传算法解决多目标求解问题,对模型进行计算,最大限度地挖掘资源系统内在的潜力,实现水土资源可持续利用的发展目标。以西安市浐灞生态区为例进行了实证求解,得出了水土资源耦合最优结果,为城市化进程中水土资源系统耦合的配置研究提供依据。

Optimal Allocation of Water and Land Resource System Coupling in the Process of Urbanization

On the background of the increasing contradiction between supplies and demands of water and land resources,water and land resource system coupling is studied for the optimal allocation of the regional resources.An allocation model of water and land resource system coupling is established and genetic algorithm is used to solve the multi-objective problem.In the calculation of the model established,inherent potential of the resource system is maximally considered so as to achieve the development goals of sustainable utilization of the resources.Finally,the Chanba ecological zone in Xi'an City is taken for an example to make an empirical solution and optimal results of water and land resource coupling are obtained.The study may provide a basis for the research on the allocation of water and land resource system coupling in the process of urbanization.
