禁牧对博乐绢蒿种群和荒漠群落特征的影响
Effects of Grazing Exclusion on Population and Desert Community Characteristics of Seriphidium borotalalense
摘要
Abstract
[Objective] This project aim to explore the response of the population and desert community quantitative characteristics to grazing exclusion, and make clear its dynamic changes in different growth peri-ods in the hope of providing a theoretical basis for the scientific grassland management.[Method]The impor-tant value of eco-economic categories, population and desert community characteristics of Seriphidium borota-lalense after grazing exclusion four years in different growth periods ( May, July and September) were meas-ured by using the field investigation sampling method.[Result](1) The important values of semi shrub and perennial herbs in May and July in response to grazing exclusion were not significant, but in grazing exclusion areas, they were significantly higher and lower than grazing areas'6. 5% , 93. 8% in September (P<0. 05);(2) Compared with the grazing area, population height significantly was increased by 23. 1% in July, the cov-erage of population and community were significantly increased by 43. 9% and 57% respectively, and their bi-omass were significantly increased by 119. 9% and 51% .[Conclusion]Short-term grazing exclusion can in-crease coverage and biomass of population and desert community of S. borotalalense in initial grazing period, thus improving the quality of grassland.关键词
