Plant diversity and soil moisture of artificial Robinia pseudoacacia forest in loess region of western Shanxi Province
摘要
Abstract
Plant diversity and soil moisture distribution at 0~400 cm depth were analyzed for slope artificial forest of Robiniapseudoacacia (ARF)at 10a,15a,20a,waste grassland was used as control.Plant diversity below forest has been found to increase with forest age,and vegetation structure has improved.The order of total soil moisture was:waste grassland (16.61%)>20 a (10.08%)>15 a (9.54%)>10 a (8.52%). With increased forest age,the trend of soil moisture increase with drop in slope is restrained.Mature RPF has a significant effect on slope soil moisture distribution.Vertical variation in soil moisture was markedly different between ARF and waste grassland,above 15a old ARF has a stable effect on soil moisture below 100cm.ARF leads to serious soil moisture deficit.With increased forest age,moisture of 0~200 cm soil is improved,but there is no recover sign for 200~400 cm soil.This work will help to guide eco-environment construction and management of Robinia pseudoacacia in the loess region of western Shanxi Province.关键词
