[Objective] The research aimed to study the climatic resource advantage and the regional climatic suitability on Mopan Persimmon planting in Fangshan. [ Method] Based on the 31 years meteorologic data from 1981 to 2010 in Fangshan, Miyun, Yanqing and Daxing, study the climatic resource advantage and the regional climatic suitability on Mopan Persimmon planting in Fangshan was studied. [Result]The heat resource is rich as its accumulated temperature greater than 10 ℃ is above 4 200 ℃ ? D in Fangshan. In winter, the Mopan Persimmon trees in Fangshan suffer less and slight frost dangers, because of the negative accumulated temperature less than 0 ℃ is higher. There is an advantage in precipitation associated with annual precipitation above 500 mm. Due to the large daily temperature range in summer and suitable temperature in September, the quantity and quality of Mopan Persimmon can be improved, reflected in rapid accumulation in photosynthetic substances and natural fruits de-astringency. [ Conclusion ] The study provides the theoretical basis for the large spheroidal-shaped fruit optimized layout and the reasonable arrangement planter scale of Mopan Persimmon.%[目的]分析房山气候资源优势和该地区磨盘柿种植的气候适宜性.[方法]利用北京房山、密云、延庆和大兴4个气象站1981～2010年的气象资料,结合磨盘柿生物学生长特性,分析了房山气候资源优势和该地区磨盘柿种植的气候适宜性.[结果]房山≥10℃年积温在4200℃·d以上,热量资源丰富；＜0℃年负积温较高,在冬季遭受冻害侵袭次数少,程度低,有利于磨盘柿的安全越冬；房山年降水量在500 mm以上,具有降水资源优势；夏季气温日较差较高,9月平均温度在19～20℃,不仅可满足光合物质的迅速积累,也使果实自然脱涩、果皮光滑及果肉无褐斑,提高产量和品质.[结论]该研究为磨盘柿的优化布局和合理安排种植规模提供理论依据.
