摘要
耕地数量的动态变化是影响区域可持续发展的关键问题之一,分析耕地数量动态变化规律及其影响因素,对合理利用和保护区域耕地资源,实现区域经济可持续发展有着重要意义。以山西耕地数量作为研究对象,根据山西1949~2005年的统计和普查资料,分析了山西耕地数量动态变化规律,探讨了影响耕地数量动态变化的驱动因子。结果表明:50多年来,山西耕地数量变化总体上表现为先增后减,总量趋减;而人均耕地面积总体上呈现明显的下降趋势;人口增长、经济发展、农业科技进步、政策等构成了耕地数量变化的主要驱动因子。
Quantitative change of cultivated land is the key to influence regional sustainable development.It is significant to analyze the influence factors and the law of quantitative dynamic change so that the cultivated land can be utilized and protected properly and the sustainable development can also be actualized.This paper analyses the law of quantitative dynamic change and driving force of cultivated land based on the statistic and census data from 1949～2005 in Shanxi province.It shows that the total area of...
