荷兰PS1模型在雄县地区土地利用系统分析中的应用——以冬小麦种植为例

Applied PS1 of Netherlands analysising the land use system in Xiongxian county

介绍了荷兰土地利用系统分析模型PS1,利用该模型分析了雄县地区土地作为冬小麦利用类型的系统运行情况,模拟了冬小麦的适播期和适宜的播种量、现有品种的生产潜力、存在的产量差,提出了该地区土地利用的可持续应变措施,走资源节约型粮食增长之路。

The land use analysis model-PS1 was introduced in this paper. The suitable sowing date and density in Xiongxian county was simulated by using this model.The limiting factor, difference on yield, potential productivity were analyzed. The measure of sustainable development is to save resource and increase yield in this area.
