基于恢复动力学生态系统恢复建设的研究

Study of Ecosystem Restoration Construction Based on Restoration Dynamics

针对退化、半退化生态系统的恢复建设,创新性地建立了物群植物恢复模型,在生态恢复动力学的基础上,分析了物群与环境、植入物群与原有物种之间的关系,运用MATLAB进行求解,研究得出:在人工植入时,要选择蒸发系数小于固水系数的草本和灌木作为物群植入对象而非蒸发系数很大的乔木,要选择物种相近的植物作为植入对象,这样可提高生态系统物种丰富度。

Aiming at the problem of the recovery of degraded ecosystem construction, we set up a group of plant restoration model creatively on the basis of ecological restoration dynamics to analysis the relationship of the group of objects with environment, the implant group and the original species. Finally, by using the MATLAB software, we find that during artificial implant, we should choose herbal and shrub instead of arbor. Besides, we＇d better choose a plant of similar species as implanted object to improve the ecological system.
