[目的
]
探究黄土高原子午岭林区不同密度人工油松林枯落物的水源涵养功能,为该区功能导向型林分改造提供理论依据。[方法
]
于2021年8月在甘肃省合水县子午岭连家砭林场选取6种不同林分密度(2 222,3 200,4 802,6 250,7 503,9 286株/hm
2
)的油松人工林为研究对象,采用坐标综合评价法对不同密度油松林枯落物的水源涵养功能进行评价。[结果
]
①油松林枯落物的厚度和蓄积量分别介于2.78~7.30 cm和14.97~52.41 t/hm
2
,两者变化趋势均呈“单峰型”,峰值出现在林分密度4 802株/hm
2
;②林分密度3 200株/hm
2
的枯落物最大持水率(192.98%)和有效拦蓄率(152.04%)较高,而林分密度4 802株/hm
2
的枯落物的最大持水量(101.46 t/hm
2
)和有效拦蓄量(67.92 t/hm
2
)表现优良,且半分解层在枯落物降水拦蓄过程中起主要作用;③枯落物持水率(量)、吸水速率与浸水时间分别呈对数函数〔R
2
>0.956(0.962)〕和幂函数(R
2
>0.998)关系;④油松林枯落物水源涵养功能发挥较好的林分密度为4 802株/hm
2
。[结论
]
仅考虑油松林枯落物的水源涵养功能,油松林密度应调控至4 800株/hm
2
。后续应加强对油松林林冠层及土壤层的研究,并综合考虑土壤水分植被承载力及油松林水分利用规律等,最终确定油松林水源涵养功能发挥最优的林分密度。
[Objective] The water conservation function of litters of artificial Pinus tabuliformis forests in the Ziwuling forest region of the Loess Plateau was determined in order to provide a theoretical basis for function-oriented stand improvement.[Methods] In August 2021
artificial Pinus tabuliformis forests with six stand densities (2 222
3 200
4 802
6 250
7 503
9 286 plants/hm2) were selected in the Lianjiabian Forest Farm in Ziwuling
Heshui County
Gansu Province. The coordinate comprehensive evaluation method was used to evaluate the water conservation function of P. tabuliformis forests.[Results] ① The thickness and volume of litters ranged from 2.78 to 7.30 cm and from 14.97 to 52.41 t/hm2
respectively. With the increase of stand density
the thickness and volume of litters showed a "single peak" change
with the peak appeared at 4 802 plants/hm2. ② The maximum water-holding rate (192.98%) and effective interception rate (152.04%) of litter for the 3 200 plants/hm2 stand were higher
while the maximum water-holding capacity (101.46 t/hm2) and effective interception amount (67.92 t/hm2) of litter for the 4 802 plants/hm2 stand were excellent. The semi-decomposed layer played a major role in the precipitation interception process of litters. ③ The water-holding rate/amount
water absorption rate
and soaking time of litters showed logarithmic responses (R2>0.956
0.962) and a power function response (R2>0.998)
respectively. ④ The water conservation function of litters was better when the density of the P. tabuliformis forest was 4 802 plants/hm2.[Conclusion] When only considering the water conservation function of litters of an artificial P. tabuliformis forest
the density of the forest should be 4 800 plants/hm2. In the future
research on the canopy and soil layer of the P. tabuliformis forest should be strengthened. The soil moisture vegetation bearing capacity and the water utilization law of the forest should be comprehensively considered to determine the stand density of the forest that provides the best water conservation function.
