广东省种植业系统能值分析

应用能值（ＥＭＥＲＧＹ）分析理论和方法，分析广东省种植业生态系统环境资源基础和经济特征，并与发达国家比较，结果表明，广东省种植业系统的发展程度相对较低，应进一步提高种植业的能值投入，重点是提高农业科技含量和可更新资源能值投入及科学管理力度。

Emergy Analysis for Planting System of Guangdong Province

The planting system of Guangdong province is evaluated by using energy and emergy analysis theory. The results show that the emergy input level of planting system in Guangdong is lower than that in developed countries, Which suggest the emergy input should be increased. The focal point of emergy input is to raise the level of farming technology and increase renewable resource emergy input, especially using agricultural ecolopcal engineering technology and biotechniques.
