吉林省农田生态环境问题及其对粮食生产的影响

详细叙述了吉林省农田自然环境、面源污染和耕地土壤退化现状，产地环境变化对粮食产量的影响。回顾了主要气象灾害、面源污染及耕地质量退化形成的原因，分析了30年来，粮食产量波动规律及自然灾害对农业生产造成的经济损失。以此为基础，提出了解决吉林省粮食生产可持续的关键技术措施，认为科学施肥，提高利用率，增加土壤有机质，提高耕地生产力是解决粮食可持续的关键技术环节。粮食可持续关键技术的有效实施，可以促进吉林省农田生态环境的改善，增加粮食品质，保障粮食生产可持续发展。

Problems of Farmland Ecological Environment and Its Effect on Food Production in Jilin Province

In this paper, farmland environment, the non-point source pollution, farmland soil degradation and influence of environment change on food production in Jilin province were analyzed. The reasons for the major meteorological disasters, non-point source pollution and land degradation were reviewed. Grain production fluctuation rule and economic losses caused by natural disasters on agricultural production were analyzed for 30 years. On this basis, the key technologies of sustainable food production were put forward in order to improve farmland ecological environment, increase food quality and guarantee the sustainable development of grain production. Our opinions were that scientific fertilization, improving the utilization rate, increasing soil organic matter and improving cultivated land productivity were the key to solve grain sustainable development.
