分析1995—2004年西辽河流域气候的变化特征,采用曲线对比分析法,研究各气候因子变化(气温升高、降水量减少)对该地区的农业总产值及农、林、牧、渔业各产值的影响。结果表明:气温升高、降水量减少使该地区各产业产值升高,提出提高该地区农业生态系统生产力的对策,以促进区域农业生产。
分析1995—2004年西遼河流域氣候的變化特徵,採用麯線對比分析法,研究各氣候因子變化(氣溫升高、降水量減少)對該地區的農業總產值及農、林、牧、漁業各產值的影響。結果錶明:氣溫升高、降水量減少使該地區各產業產值升高,提齣提高該地區農業生態繫統生產力的對策,以促進區域農業生產。

The paper analyzed climate change characteristics of Xiliao river valley from 1995 to 2004.Through the contrast and analysis of curve,it studied the effect of various climatic factors change(temperature increase,precipitation reduction) on local total agricultural output value and agricultural,forest,herd,fishery various output values influence.The results showed that output value of various industries increased with temperature increase and precipitation reduction.Some countermeasures were proposed to improve the productivity of agricultural ecosystem in the local,in order to promote the regional agriculture production.
