【摘要】：进行耕地质量预警分析,提前反映耕地质量变化趋势,对提高耕地质量和保护粮食安全具有重要意义。本文从生态经济系统的角度出发,以人地关系、耕地利用投入水平、生态环境背景和耕地效果及投资潜力四个方面为主要因素,构建佳木斯市耕地质量预警分析模型,运用回归分析法和指数和法对2008年—2020年的耕地质量进行预测预警。结果表明,随着时间序列的延伸,指标值总体上呈上升趋势,其中,2008年—2010年、2013年—2014年,佳木斯市耕地质量处于中警状态;2011年—2012年,耕地质量处于重警状态;2015年—2016年,耕地质量处于轻警状态;2017年—2020年,耕地质量处于无警状态。最后,从控制人口数量、盘活存量土地、改造中低产田、治理农田污染、加大农业投入和建立耕地质量动态监测体系等方面提出针对性措施。
[Abstract]:It is important for improving the quality of cultivated land to improve the quality of cultivated land and protecting the security of grain. From the angle of eco economic system, this paper is the main factor of four aspects: human land relationship, cultivated land use input level, ecological environment background, cultivated land effect fruit and investment potential. The early-warning analysis model of the quality of the cultivated land in mousse City, using the regression analysis method and the index and method to predict the quality of cultivated land from 2008 to 2020. The results show that, with the extension of the time series, the index values are generally on the rise, in 2008 to 2010 and 2013 to 2014, the quality of cultivated land in Jiamusi is in the state of middle police; In 2012, the quality of cultivated land was in the state of heavy police; from 2015 to 2016, the quality of cultivated land was in the state of light police; from 2017 to 2020, the quality of cultivated land was in the state of no alarm. Finally, it was put forward from the aspects of controlling the population, living the stock of the stock, reforming the middle and low yield fields, controlling the pollution of the farmland, increasing the input of agricultural industry and establishing the dynamic monitoring system of the quality of the cultivated land. Targeted measures.
