At last,We carry out stability asssessment about the vegetation in virtue of the model builded in this plot.We calculate the vegetation's ecological water requirement on May 2004: canopy of Robinia pseudoacacia L require 5.2mm, Top of Melilotus albus Desr require 32.2mm, Bottome of Melilotus albus Desr require 8.6mm, Layer of soil require 17.6mm, totalize 63.6mm,Which more 22.33 mm than the contemporaneous rainfull 41.27mm.
最后通过本次研究构建的模型对项目区植被进行了稳定性评价,计算出2004年5月份复合植被的生态需水量,分别为刺槐冠层5.2mm,草木樨上层32.2mm,草木樨下层8.6mm,土壤蒸发17.6mm,总计63.6mm,这个结果比当月的多年平均(1980-2002年)降雨量41.27mm多出了22.33mm.6月初白花草木樨收割以后,次生茬生长缓慢,我们假设草木樨没有被收割,分别计算了6月和7月的生态需水量,6月份生态需水为85.64mm,7月份为78.41mm,发现6月份水分亏缺依然严重,7月份降雨完全可以满足复合植被的蒸散需求。
