| 摘 要： | 本文在不同载畜率条件下对生长旺季荒漠草原植物群落特性和绵羊体重进行了比较,旨在为草地适宜载畜率的确定提供基础数据。研究结果表明:植物群落总盖度、高度、地上生物量随着绵羊载畜率增大均普遍降低;植物重要值无芒隐子草、短花针茅、冷蒿、阿氏旋花始终占优;绵羊个体增重和日增重均表现为轻牧>中牧>重牧,公顷增重随载畜率升高表现为先增加后减小的趋势。

| Abstract: | This study compared the vegetation community condition on desert steppe in August under different stocking rate,and analyzed the influence of stocking rate on vegetation condition and sheep weight,aiming to provide theoretical basis for rational utilization on grassland grazing.The result shows that: with increasing stoking pressure,the plant total coverage,height,aboveground biomass decreased respectively;the IV of Stipa breviflora,Artemisia frigida,Cleistogenes songorica,Convolvulus ammannii approached do... |
