Method for maintaining stability of biodiversity in a desert-oasis transition zone
By quantitatively evaluating the synergistic relationship between aboveground vegetation and the soil seed bank, differentiating reseeded species were selected and allowed to grow naturally, solving the problem of maintaining biodiversity stability in the transition zone between northern desert and oasis, and achieving a synergistic effect of vegetation community stability and natural regeneration.

Abstract
本发明涉及生物生态修复技术领域，本发明提供一种荒漠绿洲过渡带的生物多样性稳定性维持方法，其包括在待实施区域内获取地上植被物种组成数据和土壤种子库物种组成数据；计算地上植被与土壤种子库在物种组成上的相似性指数S；判断相似性指数S与补播阈值T的大小关系；基于物种丰度与物种指示分析将需要补播的区域内的物种构建丰度候选物种库、目标区指示物种库和邻近区指示物种库；结合目标区域相邻稳定群落的地上植被密度、目标区域现有植被密度及种源缺口，确定各物种的目标建植密度，并计算实际播种量；按照优先补播物种、补充补播物种和辅助补播物种形成补播实施方案。借此可有效维持荒漠绿洲过渡带的生物多样性稳定性。
