辽源地区农业生态气候资源区划探索

农业生态气候资源调查和分区,是农业自然生态资源和农业区划的组成部分,是按自然规律和经济规律发展生产,实现农业可持续协调发展的科学依据之一。笔者根据辽源地区的农业自然气候资源,参照该地独特的地势地貌,采用以热量和水分因子为主导指标,以4～9月生长期降水量为辅助指标的综合套叠方法,将辽源地区划分为西北部温暖湿润区、中南部温凉半湿润区、东部冷凉半湿润区3个农业生态气候区,旨在为当地党政机关合理开发利用气候资源,科学调整农业结构和布局,减轻和避免气候灾害,提供科学依据和参考。

The Exploration on the Regionalization of Agriculture Ecological Climatic Resources in LiaoYuan Quarter

The Investigation and regionalization of agriculture ecological climatic Resources, is the part of agriculture natural ecological resources and the rcgionalization of agriculture, and one of the basis of advancing production and rcalizfng the sustainable development of agriculture, according to the natural order and the economic trend. This paper focus on the 3 LiaoYuan Regionalization mild - wettish zone in the northwest part, warm - cool half wettish zone in south central part and cold - cool half wettish zone in east part, according to agriculture natural climatic resources in LiaoYuan, and refer to the local unique physiognomy and , apply the heat and moisture factor target - oriented, relying on Precipitation in growth period of April - September as the Auxiliary index of General Ways invagination. The research aims at providing the scientific basis and reference for the Party and government organs to develop reasonably and make use of climatic resources, and adjust scientifically the agricultural structure and layout, and mitigate and prevent climate disaster.
