典型草地生态监测敏感因子筛选研究

选择甘肃省有代表性的草地生态环境———天祝县草地生态环境,进行生态环境监测指标体系敏感因子的筛选研究。通过实验、调查,收集大量数据资料,初步筛选、确定草地生态环境监测敏感因子,对所选敏感因子进行计算机处理与分析,确定敏感因子相关因素,从而建立数学模型;验证、修改和完善模型,最终建立草原生态环境监测系统简洁、高效的敏感因子指标体系,为建立和完善生态环境监测系统,准确、客观地评价生态环境奠定基础。

Research of ecology monitoring sensitive factors' screening in typical meadow

Developing western regions,establishing eco_environment is in the first place.So we need a series of normative and effective methods to monitor the characteristic,evolving trend and the problems,show the actuality and changing trend of eco-environment,providing the evidence for the establishment of which,turning the monitor methods from intendance to guidance.Above all,we must construct the indicator system.The author selected Tianzhu meadow eco-environment as typical region in Gansu province,screening the sensitivi factors.From experiment,investigation and collecting dates,the author screened the sensitive factors primarily.Also,the author analysed the factors by PC,confirmed the relative factors,constructed the mathematics model,at last,established the compact and effective indicator system.
