Analysis on the Pasture Vegetation Characteristics of Typical Herders in Middle Section of the Northern Slope of Tianshan Mountain

Objective In order to select a relatively reasonable grassland use patterns and provide a scientific basis for a typical prairie family ranch,this study compared the variation of the grassland plant communities between the warm season grazing and cool-season stabling way and the traditional free grazing.MethodThe research,which was conducted in Ashili Kazak National Township of Changji City in the middle section of the northern slope for the study area,selected typical herders by means of the method of combining the household survey and field measurement.Result( 1) With the continuation of grazing time,the grassland vegetation community coverage,height,density and above ground biomass of the family ranch demonstration households and the control households all showed first increasing and then decreasing tendency,which reached the highest value in July,August. Different months grassland community coverage,height,density and above ground biomass showed August July June September. There was no significant difference( P 0. 05) between the demonstration households 1,demonstration households 2,demonstration households 3 grassland vegetation cover and the control households. There were significant differences( P 0. 05)between the demonstration households 2 and control households grassland vegetation height,density,there was no significant difference( P 0. 05) between the rest households. There were significant differences( P 0. 05) between the demonstration households 1 and control households grassland vegetation above ground biomass,there was no significant difference( P 0. 05) between the rest of the demonstration households.Warm season grazing,the barn feeding of cool-season and warm-season grazing,cold quarter grazing +supplementation production operation mode of herders pasture grassland vegetation situation was better than the traditional grazing.( 2) Grassland plant communities cover,height,density,aboveground biomass in the cage were increased by 24. 32%,23. 1%,12. 59% and 37. 61% than those outside the cage.( 3) 30 days after the fencing,the edible forage of the control households in the cage was increased significantly. The edible forage yield of the control households in the cage was the highest( 191. 26 g / m2),which were increased by39. 01%,21. 61% and 10. 67% than the demonstration households 1,2,3 respectively. The inedible forage yield of the demonstration households 1,2,3 in the cage were reduced by 68. 32%,24. 72%,43. 11% than those of the control households,in which the inedible forage yield of the demonstration households1 was the lowest( 54. 19 g / m2) in the cage,which,compared with the control households,was reduced by 68. 32%.ConclusionUnder the new mode of production of the warm season grazing and cool-season stabling,the utilization of natural grassland is better than the traditional free grazing,which can effectively alleviate the pressure of the grass,protect the grassland ecological environment and improve the grassland vegetation conditions.
