As a one of the focuses ecological research, understanding regulation plant diversity on community stability is helpful to reveal adaption environmental changes. However, relationship between and still controversial due scale effect its influencing factors. In this study, we compared changes in different (i.e., species, functional, phylogenetic diversities) three communities riparian forest, ecotone community, desert shrubs), across spatial scales 100, 400, 2500 m2), then quantified contribution soil properties by using structural equation model (SEM) Ebinur Lake Basin Nature Reserve Xinjiang Uygur Autonomous Region NW China. The results showed that: (1) differed among (ecotone > shrubs forest). all decreased with increase (2) species diversity, richness mean pairwise distance were higher than that while nearest taxa as forest shrubs. (3) Soil ammonium nitrogen total phosphorus had significant direct negative positive effects stability, respectively. also indirectly affected adjusting diversity. interaction functional diversities regulated variation scales. Our suggested greater asynchronous caused composition traits impact stability. study provided theoretical support for conservation management biodiversity functions areas.

Plant functional traits serve as a bridge between plants, the environment, and ecosystem function, playing an important role in predicting changes function that occur during ecological restoration. However, response of grassland to plant context restoration areas karst desertification remains unclear. Therefore, this study, we selected five [namely, height (H), specific leaf area (SLA), dry matter content (LDMC), root length (RL), (RDMC)], measured these along with community-weighted mean (CWM) trait diversity, combined measures 10 indexes related order investigate differences well relationship functions, under four models [Dactylis glomerata (DG), Lolium perenne (LP), + Trifolium repens (LT), natural (NG)]. We found that: 1) Margalef index Shannon-Wiener were significantly lower for species DG LP than those NG (P<0.05), while Simpson was higher former (P<0.05); 2) CWMH, CWMLDMC, CWMRDMC DG, LP, LT NG, CWMSLA (P<0.05). The richness (FRic) LT, but dispersion (FDis) Rao's quadratic entropy (RaoQ) there no significant difference or (P>0.05); 3) including productivity, carbon storage, water conservation soil conservation, highest lowest NG; 4) CWMLDMC (F=56.7, P=0.024), CWMRL (F=28.7, CWMH (F=4.5, P=0.048) main factors affecting function. results showed mixed pasture perennial ryegrass white clover most conductive This discovery has implications establishment vegetation, optimal utilization resources, sustainable development degraded ecosystems.
