林地生态效益价值评价模型

摘要

分析了林地生态效益价值的主要影响因素,主要有涵养水源价值、净化环境价值、水土保持价值、调节气候价值:给出了能处理不确定性信息的林地生态效益价值评价模型,并着重探讨了指标权重确定方法和对林地生态效益价值评价中的不确定信息的处理方法;最后实例验证了所建立的林地生态效益价值评价模型的可行性和便利性.%Main influencing factors affecting the ecology benefit value of woodland are analyzed, mainly including the water conservation value,environment cleaning value, water and soil conservation value, and climate regulation value. Evaluation model of the ecology benefit value of woodland is put forward which can deal with the uncertain information. Method for determining index weights is discussed, as well as the processing method for uncertain information during the evaluation of ecology benefit value of woodland. Finally, the feasibility and convenience of the evaluation model of the woodland ecology benefit value are illustrated with examples.
