- Title:
- The Preliminary Discussion on the Potentiality of Rainfall Resource in Yan’an City and Its Efficiency Use Models
- Keywords:
- Yan’an city; rainfall resources; potentiality; exploitation model
- 分类号:
- S273.2
- 摘要:
- 根据在甘肃子午岭，安塞墩滩和延安燕儿沟的试验观测资料，研究了梢林区植被对降水的拦蓄和消耗情况；分析了农区基本农田上和退耕还林（草）坡地上作物和植物对降水的拦蓄和土壤水分季节动态；计算了本区主要农作物和几种有代表性的乔、灌、草植物的全生育期内需水量和降水资源补给的盈亏状况；并提出了几种利用降水资源和河川径流的模式。
- Abstract:
- Based on the observation data from Ziwuling mountain in Gansu province part, Duntan in Ansai county and Yan’er catchment in Yan’an city, authors have studied the status of rainfall catchment and the use of rainwater by woodland’s vegetation.they have also analyzed status of soil moisture and that of rainwater harvesting of crops and other vegetation in either basical farmland or slope land; they have calculated the necessary amount of rainfall for growing crops and several typical trees shrubs and grasses along with their balancing of rainwater to evaporate during their whole living period.At the end, they put forward three kinds of exploitarion models for efficiency using rainfall resources and runoff of local rivers.
