摘　　要：为了研究苏尼特左旗草原生态功能价值在10年间的变化情况,笔者通过研究2000年、2005年和2010年苏尼特左旗草原固碳释氧、净化空气、涵养水源和抵御风蚀几个方面等功能,并将这些生态功能通过计算进行价值化,得出各年度草原生态功能价值。结果表明,2000年、2005年、2010年全旗草原生态功能总价值分别为3.34×109元、1.82×109元、3.49×109元,因此,10年间2005年的苏尼特左旗草原生态功能比2000年下降了41%,2010年比2000年提高了5%,说明苏尼特左旗2005年生态环境最差,分析原因可知:生态价值的高低与降雨量呈正相关,2005年降雨量显著低于其他年份,故生态功能价值最低。草原是一个复杂的生态系统,生态功能价值的研究在理论和方法都存在很多不足之处,因而本研究得到的苏尼特左旗草原生态功能价值是基于现有技术手段的一个保守的、较低的估算值。The paper aims to study the ecological function value change of grassland in Sunitezuo Banner, Inner Mongolia during 2000-2010. The ecological functions of carbon fixation and oxygen release, air purification, water conservation and wind erosion resistance of grassland in Sunitezuo Banner in 2000, 2005 and 2010 were studied and valued, and the ecological function values were calculated. The results showed that： the total value of ecological function of grassland in Sunitezuo Banner was 3.34×10^9 yuan, 1.82×10^9 yuan and 3.49 ×10^9 yuan in 2000, 2005 and 2010 respectively, which meant the ecological function of grassland in Sunitezuo Banner decreased by 41% from 2000 to 2005, and increased by 5% from 2000 to 2010, and it clarified that the ecological environment was the worst in 2005, which was caused by lower precipitation in 2005 compared with other years, and there was a positive correlation between the ecological function value and precipitation. The grassland is a complex ecosystem, since there are many shortages in the theory and methods of ecological function value study, so the ecological function values of grassland in Sunitezuo Banner calculated based on current technology are conservative and underestimated.
