通过引入土壤储水量、树冠覆盖率等指标，对鱼鳞坑整地改善土壤水分状况及其在侧柏造林中的应用效果进行分析，结果表明：采用鱼鳞坑整地可显著提高土壤含水率和土壤储水量；随着林地土壤水分状况的改善，造林保存率、林木生长量、林地生产力、郁闭成林的速度随之提高；在不同的土壤水分状况下，种群通过生物量投资与分配格局调节形成与之相适应的种群行为及个体形态特征，从而提高种群的稳定性或持久性。
通過引入土壤儲水量、樹冠覆蓋率等指標，對魚鱗坑整地改善土壤水分狀況及其在側柏造林中的應用效果進行分析，結果錶明：採用魚鱗坑整地可顯著提高土壤含水率和土壤儲水量；隨著林地土壤水分狀況的改善，造林保存率、林木生長量、林地生產力、鬱閉成林的速度隨之提高；在不同的土壤水分狀況下，種群通過生物量投資與分配格跼調節形成與之相適應的種群行為及箇體形態特徵，從而提高種群的穩定性或持久性。

Through introducing indicators (soil water storage & tree canopy coverage ) ,status of improving soil mois-ture content of Platycladus orientalis by fish-scale pit preparation & its afforestation effect were analyzed .Result shows that :soil moisture & soil water storage were significantly improved by taking fish-scale pit preparation . With the improvement of moisture conditions of forest soil ,the preservation rate of afforestation ,tree growth ,forest productivity and forest canopy increase .And in status of different soil moisture content ,the corresponding popula-tion behavior & individual characteristics were formed by biomass investment & distribution pattern to improve the stability maintenance or persistence of population .
