摘要:
耕地作为最基本的自然资源,其数量和质量的变化直接关系到粮食安全与人类的生存,是土地可持续利用研究的重要方面之一.使用于田县1979-2004年的社会经济统计资料和气象资料,选取15个人为和自然因子进行主成分分析并建立耕地动态变化的多元回归模型.结果表明:影响于田县耕地变化的主要因素是人为因素,总人口变化贡献率最大,而自然因素影响不大.虽然气候对耕地面积变化影响不大,但耕地面积变化对气候有一定影响.随着于田耕地面积的增大在一定程度上促使于田县年蒸发量和年均风速减小,进而改善于田县恶劣的自然环境.
Abstract:
The farmland is the most basic natural resources.Its amount and quality relates to the food safety and the life of mankind directly,which is one of the important aspects of keeping a sustainable land development.This paper used the data of social economy statistics and weather during 1979-2004 in Yutian County,carried on principal components analysis by selecting 15 artificial and natural factors and diverse return model of dynamic farmland.The results indicate that the main factor which influences farmland is artificial factor.The changes of total population is the biggest contribution rate and the influence of natural factor is smaller.Although the change of weather doesn’t influence on the farmland area greatly,farmland area have certain influence on the weather.With the increase of annual precipitation and the decline of average evaporation and average wind speed by the increase of farmland area,bad natural environment is improved in Yutian County.
