Water Physio-ecology of 12 Dominant Species in the Robinia pseudoacacia Community in Yan'an Gonglu Mountain
摘要
Abstract
In order to clarify the relationship between community stability and diversity of water-using mechanism of various plants in Robinia pseudoacacia community in hilly and gully region during the vigorous growth period, an experiment was conducted to compare and analyze the water relation parameters (water potential,the natural water saturation deficiency, and the critical water saturation deficiency)of 12dominant plants of R. pseudoacacia forests distributed on shade and semi-shade hillside in Yan;an Gonglu Mountain. The results were as follows: (1) the daily changes of water potential of the same plant inside and outside in forest were almost the same among of 12 dominant species, but the absolute values of water parameter of the same plant species measured at the same time were different inside and outside the forest,indicating the ability of environmental adaption, and the water parameters were different both in similar habitats and different habitats; (2) strategies of the 12 dominant species were divided into 4 types by cluster analysis which identified significant patterns associated with 4 water parameters and responses in the forest. Each of these strategy types had a distinct water balance mechanism and parameter adjusting pattern.关键词
