中国北方农牧交错带典型固沙植被种植适宜性研究
Study on the suitability of typical sand-fixing vegetation distribution in the agro-pastoral ecotone of Northern China
摘要
Abstract
To investigate the distribution suitability of sand-fixing plants and their soil moisture vegetation carrying capacity in the agro-pastoral ecotone of Northern China,three tree species(Pinus sylvestris var.mongholica,Elaeagnus angustifolia L.,and Salix matsudana Koidz.)and three shrub species(Haloxylon ammodendron(C.A.Mey.)Bunge,Hippophae rhamnoides L.,and Caragana korshinskii Kom.)were selected as the research subjects.A total of 28 environmental factors and the Maximum Entropy model(MaxEnt)were combined to evaluate the spatial distribution suitability of the above-mentioned sand-fixing plants.This study focused primarily on water limitation conditions,and the carrying capacity model was used to quantify the carrying threshold of each plant species in the suitable area.The results show that the spatial variation of sand-fixing plant suitable areas is significant.Among them:The suitable ranges of Hippophae rhamnoides L.,Salix matsudana Koidz.and Caragana korshinskii Kom.are the widest,accounting for more than 50％,and the three plants are found in the eastern,central,and western regions of the area;Pinus sylvestris var.mongholica and Elaeagnus angustifolia L.have a relatively smaller suitable distribution range,are mainly found in the western and central parts of the study area;In contrast,Haloxylon ammodendron(C.A.Mey.)Bunge has a suitable distribution range that covers only a quarter of the regional area,mainly distributed in the western part of the region.According to the soil moisture vegetation carrying capacity model,the vegetation carrying capacity per km2of sand-fixing plants in the study area is as follows:Pinus sylvestris var.mongholica 56 600-181 900,Salix matsudana Koidz.72 000-192 600,Elaeagnus angustifolia L.192 100-486 000,Haloxylon ammodendron(C.A.Mey.)Bunge 105 000-387 500,Hippophae rhamnoides L.274 900-628 700 and Caragana korshinskii Kom.118 500-377 300 trees per km2.In conclusion,this study provided a theoretical basis for ecological restoration and sustainable land management in the agro-pastoral ecotone.关键词
