长白山区热量资源推算与农作物品种布局

本文根据地理纬度、经度和海拔建立了吉林省东部长白山区热量资源的推算方程;采用地理细网格场的分析方法,推算出山区各地的热量资源状况,绘出细网格热量资源分布图,并以此为依据,制定了该山区农作物品种布局方案。

THE ESTIMATING METHOD OF THERMAL RESOURCES AND THE ARRANGEMENT OF CROP VARIETY IN THE CHANGBAI MOUNTAINOUS REGION

The estimaing equations of the thermal resources in the Changbai Mountainous Region were developed by using the data of climatological stations in the mountains, in accordance with the multiple regression analysis between the thermal resources and geographical factors. The amount of many thermal factors in every regions of the mountain were calcuated and the crop variety arrangement was devised. The distribution of the thermal resources in this region is out of balance and the variation of the variety in every region is greater.In the southwest hilly region,the thermal resources are plentifuler. It is suitable for growing the late and middle ripening varieties. The mountains in the central region .where the resources are meagrer,are only suitable for growing early ripening varieties. Some of regions,intervening in the hill and middle mountain,are suitable for growing the early and middleearly varieties.
