Abstract:Myrica rubra is one of the famous and characteristic fruit in Zhejiang Province, where the climate is very befitting to its planting, but the irrational distribution restricted its development. Therefore, this study screened out climate division indexes for planting by biological characteristic and established spatial analysis model for the division indexes relating to longitude, latitude and height above sea level. This study, using the sum method of weighting exponent, graded quantitatively for the eleven division indexes by dint of landform data of Zhejiang with a scale of proportion is 1︰250000, DEM and Digital soil map, considering integratedly various factors including climate factor, gradient, slop direction, height above sea level, soil type and soil quality, established the judgment matrix of the division index for Myrica rubra planting. The distributed chart of the synthesis indexes was obtained through making superposition analysis of the adaptability grade chart for the weighted means of the eleven division indexes. This study shielded the plots that disagree with plant Myrica rubra according to ground using actual data of Zhejiang, analyzed the distribution law of the synthesis index, plotted Zhejiang Province to three grades including optimum area, suitable area and inaptitude area. The highly suitable areas were accounted for 25.15% of the evaluated areas, mainly distributing in the foothill of Ningbo, Taizhou, Wenzhou, Lishui, Jinhua, Hangzhou and Shaoxing. The suitable areas were occupied 46.37%, and distributed chiefly in low mountains with a elevation between 500~700 m in Lishui, Wenzhou, Jinhua, Hangzhou and Quzhou. While the unsuitable areas accounted for 28.48%, distributing in high mountains above 700m in Lishui and Hangzhou. This study offered scientific opinion for programming of characteristic crop and development of Myrica rubra industry in Zhejiang.
