| 摘 要： | 本文针对我国北方干旱半干旱地区水资源短缺的问题，采用水土富集工程措施，使土壤的容水能力由84.89毫米提高到243.23毫米，土壤含水总量比对照提高3.1倍，<0.1毫米的土壤粘粒比对照增加68.52%，基本解决了太行山低山丘陵区干旱阳坡“造林难”的问题，使干旱阳坡的石榴经济林平均亩产达80.4公斤，每亩年获经济效益482.4元。

| Abstract: | In order to solve the problem of water shortage in the arid and semiarid region in Northern China water and soil accumulation engineering was carried out.Results showed that the soil water holding capacity was increased from 84.89mm to 243.23mm,soil moisture was 3.1 times higher averagely,and soil particulars with diameter less than 0.1mm was increased by 68.52% compared with the control.The serious problem which hold down the survival percentage of afforestation on the dry sun slopes in Taihang hilly region was generally solyed.The annual fruit output of pomegranate planted by this engineering was 80.4kg/mu with annual economic benefit at 482.4 yuan/mu. |
