南昌井水位对远震的同震响应分析

通过对2001—2008年间139次震例数字化资料的总结,定性分析了南昌井水位资料对强远震的响应情况,并采用二阶回归方法对模型进行优化和定量分析。研究认为:南昌井水位资料对强远震响应较好,同震响应幅度与震级、震中距综合相关,响应距离随震级增加而增加,但在各震级档中均存在距离上限。

Improvement of Ecological Footprint Method and Application in Henan Province

Abstract

The measure of sustainable development has always been an important and difficulty subject, and the major evaluation model has three types: indicators based on system theory and methods, indicators relied on economic valuation of the environment, sustainability indicators including biophysical assessments. The ecological footprint analysis initiated by William E. Rees, one of the indicators including biophysical assessments, gets rid of the defects of the other models. Ecological footprint has gradually become popular on account of the measuring indexes based on scientific theory, innovative thought-way and its wide adaptability. This paper introduces the conception and computation method, making a progress and making up for the method of ecological footprint, and finally, makes an application analyses through Henan province regional sustainable development.
