为解决因干旱少水导致黄土高原树木生长不良的问题,利用径流林业的理论,对不同集水面积和集水措施对油松生长环境的水量平衡做了研究。结果表明,不同的集水面积和坡面处理措施对植树带的来水量、耗水量和水量平衡都产生较大影响。其中集水面积5m2的水分盈余比集水面积3m2的要多,采取压实拍光措施(PG)的水分盈余比未采取措施(CK)的要多。
In order to solve the problem of poor growth of trees in the Loess Plateau caused by drought and little water, this paper studied the water balance of the growth environment of Pinus tabulaeformis by using the theory of runoff forestry. The results showed that different water catchment areas and slope treatments had a great impact on water balance, water consumption and water balance of tree planting belt. Among them, the water surplus of 5m2 in catchment area is more than that of catchment area of 3m2, and the compaction and photoperiod (PG) has more surplus in water surplus than that without taking measures (CK).
