英文摘要	Mongolian pine plantations composed of Pinus sylvesiris var. mongolica Litv. are used for desertification control and restoration of degraded land in arid and semi-arid regions. For the propose of evaluating the hydrological functions of forest litter and soil of Mongolian pine plantations in Mu Us Sandy Land, China, the 60 standard sampling points (10 stand density gradient plots, 6 reduplicate) were investigated. The results indicated that: (1) The thickness and water-storage capacity of half-decomposed forest litter were slightly higher than those of non-decomposed forest litter. The sequence of water-storage capacity of forest litter followed by P-IV>P-III>P-VII>P-VII>P-VI>P-V>P-X=P-IX> P-II>P-I (Non-decomposed forest litter), P-III>P-IV> P-X>P-IX>P-VIII>P-VI>P-VII>P-V>P-II>P-I (Half-decomposed forest litter). The range of maximum water-holding capacity and effective water-holding capacity of forest litter among plots were 2.46-8.23 t.hm(-2) and 0.043-3.65 t.hm(-2) respectively. (2) Logarithmic function model was used to fit the relationship between water-holding capacity of forest litter and soaking time, and exponential function model was used to fit the relationship between water-absorption rate of forest litter and soaking time, the correlation coefficients of these models were above 0.500 (R-2 equal to 0.654-0.971 and 0.514-0.921). (3) There are no obvious differences in water content, bulk density and maximum water-holding capacity of soil between surveyed plots, which were 8.94-16.54%, 1.10-1.66 g.cm 3 and 200.43-266.43 t.hm(-2) respectively. While, the non-pore porosity of soil between surveyed plots fluctuated greatly, and the variation range was 0.99-4.32%. And the hydrological effects of soil in P-III and P-IV were determined to be the best, while P-I was the least. (4) The variation of initial and stable infiltration rate of soil among surveyed plots were 8.20-16.34 mm.min(-1) and 0.11-0.89 mm.min(-1). (5) The water-holding capacity of soil is far greater than that of forest litter layer, and afforestation density plays an important role in improving the soil structures and the infiltration capacity of soil. In conclusion, according to the results, P-III and P-IV plots were determined to be the optimal afforestation density (1200-1250 tree.hm(-2)) with the most favorable hydrological characteristics of forest litter and soil. And our results suggest that thinning should be done timely in study area to prevent the recession of forest stand. Besides, it is uncertain whether Mongolian pine can be planted in large scale or in high density in arid or semi-arid regions, which should be dig into further research.
