试验样地设置在大兴安岭地区新林林业局新林林场106、107、108、109林班内。以大兴安岭落叶松针叶林为研究对象，将立地条件相同的原始林样地作对照，选取抚育强度为62．3％、16．75％、20．86％、27．85％、40．01％、56．51％、67．25％7个样地，收集枯落物并测定水质，应用灰色关联度法，综合评价抚育强度对枯落物及水质影响。研究表明，抚育强度为40．01％时，枯落物蓄积量最大，为8．66 t／hm2，水土保持能力最佳，同时与水质指标的灰色关联度最高（0．955），即水源水质最好；抚育强度为27．90％时，枯落物有效拦蓄水量最大，为17．77 t／hm2。综合评价结果是抚育强度在27．90％～40．01％时的抚育效果最好。

In 106 th, 107 th, 108 th, 109 th block of Xinlin Bureau,Daxing ’ an Mountains, we took the Larix gmelinii to choose eight subjects of different fostering intensities ( 6.23%, 16.75%, 20.86%, 27.85%, 40.01%, 56.51%, and 67.25%) with CK.By collecting the litter and measuring the water quality, we used grey system theory to evaluate the water quality comprehensively.When the fostering intensity was 40.01%, the litter accumulation of water absorption was the largest of 8.66 t/hm2 with the best conservation capacity of the water and soil.In 27.90%, the efficient storage was best with 17.77 t/hm2. When the fostering intensity was in 27.90%-40.01%, the fostering effect was the best.
