- Abstract:
-
Based on the positioning experimental in semi-arid loess area, factor (FA) and clusters (CA) analysi were used to evaluate the effect of soil physical and chemical properties by selecting 10 similar conditions criteria, and 9 soil properties that reflect the quantitative indicators. By factor analysis, four soil common qualities (i.e., soil available nutrient supply factors, soil total nitrogen and pH factors, soil structure, water retention factor, soil bulk density factor) were derived from 9 soil indicators. The FA results show that there are significantly different among different forest types based on 4 common factors; different stands focus on different improvement on soil physical and chemical properties. The type of Larix gmelinii and Pinus tabuaeformis mixed gets low score, which may be deep-rooted trees have little effect on surface soil, the top three integrated patterns with the highest score include Robinia pseudoacacia (stand density 1200~1700 plant/hm2), followed by Robinia pseudoacacia CH2 (1200 plant/hm2)>Robinia pseudoacacia CH1(1700 plant/hm2)>Robinia pseudoacacia CH5(1625 plant/hm2), Robinia pseudoacacia as the dominant species in the research area, which significantly improved soil physical and chemical properties, suitable Robinia pseudoacacia density is more prominent on improving soil physical and chemical properties.
