Analyze the Influence of Increases of Population and Progress of Agrotechnology on Farmland Utilization & Environment

研究目的:分析人口数量增加、农业技术进步对土地利用强度和环境的渐进影响。研究方法:静态分析和比较静态分析法。研究结果:人口数量增加和第一类农业技术进步将导致土地利用强度增加,对环境产生一定的负面影响。第二类农业技术进步会减轻土地利用强度,有利于土地可持续利用。研究结论:人类社会发展过程中,随着人口的增加和第一类农业技术的进步,要高度重视第二类农业技术的研究与开发。

The purpose of this paper is to analyze the influence of population and progress of agrotechnology on farmland utilization and environment.Methods of static analysis and comparative static analysis are employed.The results indicate： Increases of population and first type of agrotechnology are important social variable for the increases of farmland utilization intensity,second types of agrotechnology improves the land bearing capacity,conducive to the sustainable use of farmland.It is concluded that,during the development of human society and the ever-increasing population,human being should cautiously utilize some of agrotechnology which can only improve the production rate of land and highly value other agrotechnology which can enhance the bearing capacity of land.
