中文摘要	【目的】本文分析了喀什地区温性荒漠生物量动态规律。【方法】基于新疆维吾尔自治区草地类型图,结合喀什地区温性荒漠类草地区域19个采样点的生物量野外调查数据,对喀什地区温性荒漠生物量动态规律进行了分析。【结果】喀什地区温性荒漠类草地单位面积生物量空间分布具有高度异质性,总生物量在83.63~4782.79 g·m~(-2)之间波动,均值为1123.14 g·m~(-2);地上生物量以灌木为主,草本生物量随海拔增高而显著增多(P<0.05),灌木生物量和地上生物量均随海拔增高而显著减少(P<0.05),地下生物量与海拔相关性不大;生物量在经纬向上均具有一定线性规律,但无显著相关性关系(P>0.05);喀什地区温性荒漠类草地根冠比较大,灌木NPP占比为62.92 %,草地生物量和NPP均与降水具有显著相关性(P<0.05),但NPP与气温相关性不大(P>0.05)。降水是影响喀什地区温性荒漠类草地生物量分布的重要因素。【结论】经纬度的变化、不同的海拔梯度、降水量大小都在一定程度上影响了喀什地区温性荒漠类草地生物量动态分布。
英文摘要	【Objective】This paper aimed to analyze the dynamic law of temperate desert grassland in Kashgar.【Method】 Based on grassland types in Xinjiang Uygur Autonomous Region and the field investigation data of 19 sampling sites in the temperate desert grassland of Kashgar region,and the dynamic law of temperate desert grassland in Kashgar was analyzed.【Result】The spatial distribution of temperate desert grassland biomass per unit area in Kashgar area had a high degree of heterogeneity,and the total biomass ranged from 83.63 -4782.79 g·m~(-2),with an average of 1123.14 g·m~(-2);The aboveground biomass was dominated by shrubs,the herbaceous biomass increased significantly with elevation (P<0.05),shrub biomass and aboveground biomass decreased significantly with elevation (P<0.05),and the biomass and underground biomass in the altitude was not relevant;The biomass had a certain regularity in longitude and latitude,but there was no significant correlation (P >0.05);The rootshoot ratio of temperate desert grassland in Kashi area was relatively large,shrub NPP accounted for 62.92 % of the total,both grassland biomass and NPP had a significant correlation with precipitation (P<0.05),but the correlation between NPP and temperature was not significant (P >0.05).Precipitation was an important factor affecting biomass distribution of temperate desert grassland in Kashgar area.【Conclusion】The biomass dynamic distribution of temperate desert grassland was affected by latitude and longitude,altitude gradient and precipitation to some extent in Kashgar region.
