[Water and soil conservation function of typical plantation forest ecosystems in semi-arid region of Western Liaoning Province].
From the aspects of surface runoff and soil erosion, this paper quantitatively studied the water and soil conservation function of five plantation forest ecosystems in semi-arid region of Western Liaoning Province. The results showed that various types of test plantation forest ecosystems were all able to reduce surface runoff and soil erosion effectively. In June - September, the monthly mean surface runoff coefficient of Pinus tabulaeformis forest ecosystem, P. tabulaeformis - Hippophae rhamnoides forest ecosystem, H. rhamnoides forest ecosystem, P. simonii forest ecosystem, and P. simonii - H. rhamnoides forest ecosystem was 10.1%, 6.5%, 2.3%, 8.6% and 5.3% of that of barren hill, respectively, and the soil erosion quantity was 2.65%, 0.96%, 0.15%, 2.32% and 0.69% of that of barren hill, respectively. Among the five forest ecosystems, H. rhamnoides forest ecosystem had the least surface runoff and soil erosion, being the best in water and soil conservation function.
