新疆地区土地资源开发利用SD模型

SD Model for the Development and utilization of Land Resources in Xinjiang

本文根据系统动力学原理和土地资源的有限性、不可替代性及动态发展特性,建立了新疆土地开发利用SD模型系统并予以具体应用。该模型由七个子块构成:(1)人口发展子块;(2)水资源开发利用子块;(3)种植业发展子块;(4)林业发展子块;(5)畜牧业发展子块;(6)城镇用地发展子块;(7)交通用地(公路)发展子块。文中主要介绍模型构思,以种植业子块为例,对模型进行描述。并介绍了应用结果。

A system dynamics (SD) model system for the development and utilization of Xinjiang land resources was established in terms of SD principles as the limitation, non-replacability and dynamic development feature of land resources. The system consists,of the following seven subsystems: ① population development, ② water resources development and utilization, ③ crop planting development, ④ forest development, ⑤ animal husbandry development, ⑥ the variation of the land resources used for city and town expansion, ⑦ the variation of the land resources used for transportation installation (highway) construction. The paper mainly presents the idea for constructing the model, and taking the crop planting development subsystem as an example, describes the -subsystem in detail and gives the results of the subsystem.
