摘要: 利用陕晋黄河两岸32 个县1985—2014 年气象观测资料和地理信息数据,基于GIS技术对该区的中阳木枣进行气候适宜性区划,可为气候变化背景下黄土高原丘陵区中阳木枣产业结构调整和可持续发展提供科学依据。在综合分析黄土高原丘陵区中阳木枣气候适宜性、气候变化对陕晋两地红枣生产影响实地调查结果,以及陕晋两地红枣典型丰产年和受灾年关键生育期气象条件的基础上,建立了黄土高原丘陵区中阳木枣气候适宜性评价指标体系,基于GIS 技术完成研究区域各区划指标的精细化空间小网格模拟推算,利用模糊综合评判法,结合坡向地形因子对黄土高原丘陵区中阳木枣气候适宜性进行区划与评价。研究表明:适宜区主要分布在陕晋黄河及其支流沿岸,海拔高度730~1100 m的阳坡滩地、河谷和丘陵坡地;建议北部适宜区适当扩大中阳木枣种植面积,中南部适宜区和次适宜区应及时调整产业结构,改良种植抗裂品种,同时加大基础配套设施建设,促进黄土高原丘陵区红枣产业健康持续发展。

Abstract: Based on the meteorological data and geographical information at 32 weather stations from 1985 to 2014 in the coastal region of the Yellow River, by using GIS technology, authors built the climatic division for Zhongyang Jujube in order to provide scientific basis for its industrial structure adjustment and sustainable development. Firstly, through the comprehensive analysis of climate suitability characteristics of Zhongyang jujube, the investigation of climate change impact on its production and the meteorological conditions of key growth periods in typical yield and disaster year in Shaanxi and shanxi, the climate suitability evaluation system of Zhongyang jujube in the Hilly Area of Loess Plateau was established. Next, small grid reckon model was established to calculate the spatial distribution for each regionalization index values in this area. Thus, based on GIS the distribution graph of the climate suitable planting areas of Zhongyang jujube was formed by using comprehensive evaluation method according to the topographic slope. The results indicated that the suitable regions for dried jujube plant are mainly distributed Sin the flood land, river valley areas and hilly sloping land ofScoastalSShaanxiSand ShanxiSthe Yellow River and itsStributaries, with altitude from 730Sto 1100 meters. The northern suitable region may expand the planting area appropriately; The central and southern suitable and sub-suitable areas should adjust the industrial structure, improve the planting crack varieties, while increasing base infrastructure construction to promote the jujube industry healthy and sustainable development in the Loess Plateau.
