摘要：运用生态经济学理论与研究方法,对乌兰布和荒漠生态系统2009年防风固沙功能价值进行了初步评估。结果表明:乌兰布和荒漠生态系统2009年防风固沙物质量为2.75×108t;价值量为44.204×108元。其中,减少农田经济损失价值为8.148×108元;减少草地经济损失价值为0.407×108元;保持土壤肥力价值为31.962×108元;减少泥沙淤积灾害价值为1.65×108元;减少交通运输经济损失价值为2.037×108元。可以看出,荒漠生态系统具有巨大的生态经济价值,因此,建议在今后的开发与建设过程中应对荒漠生态系统进行保护与合理利用。评估结果可为生态环境建设政策的制定及国家宏观决策提供一定的科学依据。
The service functional and its value of wind-breaking and sand-fixing were evaluated based on the theory and method of ecological economics in Ulan Buh desert ecosystem.The results showed that the material mass of wind-breaking and sand-fixing was 2.75×108t,and the value was 44.204×108Yuan.It proved that there were a great of ecological economic values in desert ecosystems,so the desert ecosystems should be protected and reasonably exploited in the process of development and construction in the future.The evaluation result is able to provide a scientific basis for the formation of ecological environment construction policy and national macro decision-making.
