| 摘 要： | 塬面苹果园、农田和其它主要土地利用方式的比较研究表明,苹果园的水分环境效应表现为土壤高入渗率、降雨低产流率和强烈的蒸腾耗水作用形成的土壤低湿层,使土壤水库对干旱的调节作用丧失,导致苹果产量随年际降雨呈现较大波动。随着苹果种植面积的扩大,这种水分环境效应将加强土壤、植物、大气间的水分小循环,削弱降雨转化为地表水和地下水的比例,最终影响区域水资源的数量和果业的持续发展。

| Abstract: | The water status in the apple orchards,cultivated land and the other land using styles in the area of loess plateau where usually having dry weather were comparatively investigated.The results showed that there was a high infiltration rate,low runoff and dry soil pro file caused by strong transpiration in apple orchards.Regulating drought function of soil reservoir was lost,leading to the yield of apple fluctuating with annual rainfall.The water environmental effect of the increasing apple planting area would strengthen small water cycle among soil-plant-atmosphere,weaken the proportion of surface water and ground water exchanged from rainfall,and finally in fluence the quantity of region water resource and the sustainable develop-ment of fruit industry. |
