Abstract:

We investigated 27 different plant community allocation modes for a protection greenbelt in the alluvial fan gravel desert area in southern Urumqi. The ecological effects of different plant community allocation modes were evaluated and ranked using the analytic hierarchy process and fuzzy comprehensive evaluation model. We found that the allocation of several species was beneficial: Pinus sylvestris var. mongolica-Atriplex cana-Chondrilla piptocoma+Seriphidium transiliense, Ulmus pumila-Hippophae rhamnoides-Chondrilla piptocoma+Clematis songorica, Ulmus laciniata-Hippophae rhamnoides-Chondrilla piptocoma+Acroptilon repens, and Elaeagnus angustifolia-Atriplex cana-Chondrilla piptocoma. The expansion of these optimal allocation modes was analyzed based on the similarity of ecological effects of plant communities and landscapes. The allocation modes composed of high tridimensional green biomass, high coverage, and strong adaptability are proposed as being optimal. This study provides a theoretical basis and technical support for the construction of a protection greenbelt in an arid gravel desert region.
