| 摘 要： | 研究目的:分析黑龙江省的水田规模与分布变化,探讨气候变化对水田的影响,预测未来水田变化趋势。研究方法:文献资料法和常规数理统计方法。研究结果:近30年黑龙江省水田面积大量增加,占耕地比重逐步提高;各县市水田规模、增量和增幅差别较大,以中部地带增加最为明显,水田分布范围向东向北扩张;气温升高和热量条件改善是水田分布范围扩大的重要原因,气象灾害导致水田面积和水稻产量波动;未来水田面积将持续增加,但趋势将减缓。研究结论:黑龙江省水田规模与分布的变化与气候变化密切相关。

| Abstract: | The purposes of this paper are to analyze scale and distribution variation of paddy fields of Heilongjiang Province,explore the impacts of climate change on paddy fields and predict the trend of paddy field in the future. Methods employed include documentation and normal mathematical statistics.The results indicate that(1)paddy fields of Heilongjiang Province in recent 30 years have been growing considerably,the proportion of paddy fields in cultivated land has gradually increased;(2)there are great differe... |
