Aiming at the chaos complexity activities which may occur during the evolution process of mining area ecosystem, we emphatically analyze the application of associated dimention judgment method and Lyapunov factor analytic approach based on phase space restructuring technique. We can ascertain whether mining area ecosystem have chaos characteristic or not according to these methods. It has important theory value for complexity research of mining area ecosystem.
其次,针对矿区生态系统演变过程中可能出现的混沌复杂行为,基于相空间重构技术我们重点分析了关联维数判断法和Lyapunov指数分析法的应用,依据这些方法,我们可以定量的判断矿区生态系统是否具有混沌特性,这对于我们进行矿区生态系统的复杂性研究具有重要的理论价值。

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。
