| 中文摘要: |
| 通过对西安南郊吴家坟、长安区郭杜镇大学城和双竹村附近丰水年(年降雨量883 mm)麦地、玉米地土壤含水量的测定,以及与正常年份该地土壤含水量的对比,研究丰水年该地区农田0~6 m土壤含水量的变化。结果显示,正常年份西安地区麦地0~2 m土层含水量高于12%,2~6 m土层含水量高于13%;丰水年西安地区麦地0~2 m的土壤含水量在18%以上,2~6 m土层含水量达24%以上,远远高于正常年份这一层位的土壤含水量。分析得出,西安地区农田深层土壤含水量高的主要原因是重力水带分布范围大于或等于农作物的强烈耗水层范围。 |
| 英文摘要: |
| Based on the determination of soil moisture in farmlands in south of Xi’an and Chang’an,the changes of soil moisture from zero to six meters in different rainy year are studied in this paper.The results show that the soil moisture is higher than 12 percent from zero to two meters,soil moisture in farmland is normal.In plentiful rainy year,the soil moisture from zero to two meters is higher than 18 percent and the soil moisture from two to six meters is higher than 24 percent,which are higher than that of the layers in normal year.It shows that Xi’an district is the place suitable to the flat root crops. |
