【摘要】：将区域水土资源联合配置的多学科综合与新技术的应用成果相结合,以水土资源联合配置的体系为基础,定量刻化了水资源、土地资源配置系统与社会、经济、环境发展之间的互动影响关系,将包括需水、供水、土地需求及供给和生态环境影响等相关的水资源、土地资源联合配置的要素,与社会、经济、环境系统耦合成一个复杂的水资源-土地资源-社会经济-生态模拟系统,利用基于图论改进的流率基本入树的系统动力学(SD)规范建模方法,建立起了比较完整的区域水土资源优化配置的系统动力学流率基本入树模型。运用该模型,对位于苏南丘陵地区的句容市按照不同水土资源联合配置方案(情景)的水资源、土地资源与社会经济环境耦合系统进行模拟计算,该计算结果可为水资源、土地资源的联合统一管理提供基础支撑。
[Abstract]:Based on the system of joint allocation of water and soil resources, the system of water and soil resources, the system of land resources allocation and the society and economy are quantitatively engraved by combining the multidisciplinary integration of regional water and soil resources allocation with the application of new technology. The interaction between environmental development will include water demand, water supply, land demand and supply and ecological environmental impact, elements of land resources joint allocation, social and economic, The environmental system is coupled into a complex simulation system of water resources, land resources, social economy and ecology. The modeling method is based on the improved system dynamics (SDD) based on graph theory. A complete system dynamic flow rate model for optimal allocation of regional water and soil resources was established. The model is used to simulate and calculate the coupling system of water resources, land resources and social economic environment in Jurong city, located in the hilly region of southern Jiangsu, according to different water and soil resources joint allocation schemes (scenarios). The results can be as follows: water resources. The United management of land resources provides basic support.
