本地区丽江、宁蒗、永胜、华坪四县均位于滇西北高原,境内地形错综复杂,气候垂直差异十分显著,形成了千差万别的农业气象条件和丰富多采的水稻品种资源。但因稻区分布于海拔一千公尺到二千七百公尺的河谷和高原平坝间。热量条件不太充裕,加之耕作较粗放,致使单产低而不稳。本文从农业气候角度分析热量条件与水稻丰、欠的关系,并探讨相应的措施以期趋利避害,提高水稻生产水平。一、丽江地区水稻生产概况丽江地区各县相对产量(相对产量=实际产量/多年平均产量×100％),根据 The four counties of Lijiang, Ninglang, Yongsheng and Huaping in the region are all located in the plateau of northwestern Yunnan. The inland terrain is intricate and the vertical differences among climates are very significant. Different kinds of agro-meteorological conditions and rich and varied rice germplasm resources have been formed. However, the rice area is distributed between valleys and plateaus at an altitude of 1,000 meters to 2,700 meters. Not enough heat conditions, coupled with more extensive farming, resulting in low yield and instability. This paper analyzes the relationship between heat conditions and rice abundance and underdevelopment from the perspective of agricultural climate, and discusses the corresponding measures in the hope of avoiding disadvantages and increasing the level of rice production. First, the overview of rice production in Lijiang Prefecture Lijiang Prefecture relative yield (relative yield = actual yield / average yield for many years × 100%), according to
