摘要
依据蓝莓生物学特性及生长环境要求,确定影响丹东市蓝莓产量或品质的主要气候适宜性指标为1月最低气温、≥10℃积温、果实成熟期降水量,并综合运用判断矩阵法、加权求和法及GIS空间分析法,开展丹东市蓝莓种植气候适宜性区划研究。结果表明:不适宜区主要分布于宽甸县境内,包括双山子、八河川、石湖沟等乡镇,该区域1月最低气温偏低,热量分布不均衡,且果实成熟期降水偏多,不建议发展蓝莓产业。次适宜区主要分布在丹东市北部地区,该区域1月最低气温偏低,热量条件稍好,果实成熟期降水量适宜。适宜区主要分布在丹东市中部及南部地区,该区域1月最低气温较适宜,热量条件好,果实成熟期降水量也适宜,适合发展蓝莓产业。
According to the biological characteristics and growth environment requirements of blueberry,the main climatic indexes affecting the yield or quality of blueberry in Dandong were determined to be the minimum temperature in January,≥10℃accumulated temperature and precipitation during fruit ripening stage.The climate suitability of blueberry planting in Dandong was studied by comprehensively using judgment matrix method,weighted sum method and GIS spatial analysis technology.The results showed that the unsuited area was mainly distributed in Kuandian County,including Shuangshanzi,Bahechuan,Shihugou and some other towns.The lowest temperature in January in this area was low,the heat distribution was unbalanced,and the precipitation was high in the fruit ripening stage,so it was not recommended to develop the blueberry industry.The sub-suitable area was mainly distributed in the northern part of Dandong.The lowest temperature in January in this area was relatively low,the heat condition is slightly better,and the precipitation was suitable in the fruit ripening stage.Suitable area was mainly distributed in the central and southern parts of Dandong,where the lowest temperature in January was more suitable,the heat conditions were good,and the fruit ripe precipitation was also suitable,which was suitable for the development of blueberry industry.
