摘　　要：引入了GIS等高新科技和信息技术,采用了间距在10km以内的中尺度气象站资料和半理论半经验的散射辐射资料,使评价单元中的气候生态指标更接近于茶区的实际情况,评价单元的分辨率达20 m×20 m,极大地提高了区划成果在实际生产应用中实用性。结果表明:最适宜种植区主要集中在海拔300～800 m东南方向的括苍山区和西南大洋山区,该区温度适宜、热量充足、雨水充沛,茶叶品质好、产量较高;适宜区主要位于海拔300 m以下的低丘缓坡,热量充足、湿度偏小,产量高,但优质茶产量小,以及位于海拔800～1 000 m的高山地区,该地区热量条件较差,产量低,时有冻害发生;海拔1 000 m以上的高山和山顶,土壤贫瘠、冻害严重,不宜发展。This division brought in the information technology and other high-new technologieslike GIS technology,etc,together with the mesoscale weather station data whose spacing was within 10 km and the semitheoretical and semi-empirical scattering radiation data,making the climate and ecology index in evaluated unit,whose resolution reaches 20 m × 20 m,closer to the reality in tea planting area,and largely improved the practicality of division achievements in the producing application.The result showed that: the optimum areas were mainly distributed in Kuocang Mountain area in the southeastern and Dayang Mountain area in the southwestern,both with a elevation between 300 ～ 800 m,possessing the advantages of suitable temperature,sufficient heat,abundant rain,so that tea plant in those area had high quality and quantity.The suitable areas were chiefly distributed in two kinds:one was the foothills,which were lower than 300 m,with sufficient heat and smaller humidity,having the high output in all but low output in high-class ones;the other was the high mountains with an altitude between 800~1000 m,with relatively poor heat condition,having a low output and frost damage occurs a lot.As for the mountains and peaks above 1 000 m high,with barren soil and severe frost damage were not suitable for development.
