人工草地土壤水系统动力学模型与过耗恢复预测
- Title:
- The Systematic Dynamaic Model of Soil Moisture and It’s Over-exhausted Recovering Forecast in Artificial Grassland
- 摘要:
- 针对黄土丘陵沟壑区人工草地深层土壤水分严重亏缺问题，首次利用系统生态原理及计算机仿真手段，初步建立休闲草地土壤水分系统动力学模型，提出长历时（多年），大厚度（5m）土壤水分动态仿真和模型参数获取有效方法，预测特定地区（宁夏固原上黄试区）休闲草地不同水文年型深层土壤水分恢复年限.
- Abstract:
- For the first time, aimed at over-exhausted deep-layer soil moisture in fallow tame grassland in semi-arid area of Loess Plateau,based on system ecology and computer simulation build a soil moisture system dynamic model,put forward a practical way of parameter gaining, forecast the time limit of deep layer soil moisture recovering under different hydrologic year-types in fallow tame grassland in special area (Guyuan,Ningxia).
