基于GIS辽宁省‘红富士’苹果农业气候区划

为研究辽宁省‘红富士’苹果适宜栽种的气候分区，利用辽宁52个气象站点1981-2010年气候资料和台站地理信息，采用GIS技术对红富士苹果的热量、降水和日照等气候资源进行网格推算并予以分析。根据红富士苹果对气象条件的要求，确定了气候区划指标，并将全省划分为最适宜种植区、适宜种植区、次适宜种植区和不适宜种植区4个分区。结果表明，（1）1月平均气温和4-10月温量指数对‘红富士’苹果栽种影响最大，选二者为‘红富士’苹果气候区划指标；（2）‘红富士’苹果的发展坚持-10℃安全线原则，在辽南应主要在大连市主要发展、营口市南部适当发展；在辽西主要是葫芦岛市的西南部、朝阳市的西南部和锦州市南部；辽中应在盘锦适当发展；辽东的丹东南部沿海一带适当发展。

Agricultural Climate Regional Planning of‘Red Fuji’Apple in Liaoning Province Based on GIS

In order to research the climatic regionalization of‘Red Fuji’ apple in Liaoning Province, precipitation and sunlight in grids were established by using the principles of geographical information system （GIS）, based on climate data of 52 meteorological stations and geographic information in Liaoning Province, the climatic elements such as heat. According to the needs of‘Red Fuji’apple on climate condition, summarize suitable planting area in Liaoning Province was divided to 4 regions, which were most suitable zone, suitable zone, subsuitable zone and unsuitable zone, before giving planting suggestion, also analyzed the characters of 4 regions. （1） The average temperature of January and the temperature index from April to October made great impact on the‘Red Fuji’apple growing, and therefore chose the two factors to divide climatic regionalization of‘Red Fuji’apple. （2） The development of‘Red Fuji’apple planting areas should stick on‘-10℃ safe principle’. In south of Liaoning Province, Dalian could have rapid development, south of Yingkou City could have appropriate development. In the west of Liaoning Province, part of Huludao City, Chaoyang City and Jinzhou City could have appropriate development. In the middle of Liaoning Province, Panjin City can have appropriate development. In the east of Liaoning Province, seaside of south Dandong could have appropriate development.
