耕地生态经济系统动态监测研究

A research on monitoring the dynamics of ecoeconomic system of arable land.

在分析中国耕地生态经济系统运行的波动性、结构的复杂性、“体质”的脆弱性和调控的滞后性4个特征的基础上,指出开展耕地生态经济系统的动态监测,可使耕地管理由静态、被动状态走向动态、主动状态,实现耕地生态经济系统调控的超前性,切实有效地保护耕地。并阐述了耕地生态经济动态监测预警系统所包含的警义、警源、警兆和警度4个方面的基本内容以及构建中国耕地生态经济动态监测机制的基本思路与方法。

Based on analysis of the four characters of ecoeconomic system of arable land in China: the fluctuation in motion,complex in structure,frailty in constitution and delayed management,it is concluded that by carrying out the monitor of the dynamics of arable land ecoeconomic system,the management of arable land can be changed form static and passive states to dynamic and initiative states to realize the goals of adjustment of the arable land ecoeconomic system in advance and effectively protect the arable land. Then the basic meaning, sources, signs and degrees of the forewarning system as well as the train of thought and methods for forming the mechanisms of monitoring the dynamics of arable land ecoeconomy in China are extensively discussed in the paper.
