摘　　要：西部地区灌丛生态系统具有较高的经济和生态环境效益,可货币化生态环境效益为9 836×108元/a。在灌丛生态系统的各种生态系统公益之中,以固碳释氧的比重最大,约占58%;其次是空气净化(消除污染)的效益,约占22%;水土保持的效益约占16%。总效益与西部地区国民生产总值(1997年)相比较,相当于农业生产总值的2.8倍。The service values of shrub ecosystem had been a^essed individually. Environmental benefit which can be monetized, is 9836× 10^8 Yuan/a. Value of oxygen liberating and carbon deposition, about 58 percent, is the most among these environmental benefits, while value of air cleaning is the second, which is about 22 percent, water and soil conservation benefit is about 16 percent. Sum of these values is 2.8 times of Gross Agriculture Product of the same region.
