摘要
为了研究气候因素对区域苹果分布格局的影响,利用ArcGIS空间分析研究了黄土高原29个苹果主产市2005年、2010年和2015年苹果种植面积与年平均降水量、年平均气温和年平均日照时数的关系。结果表明:黄土高原苹果种植面积分布格局在近10年内主要向甘肃东部(天水、平凉和庆阳)、陕西中北部(延安和榆林)、山西西部(临汾和运城)和河南西部(三门峡)移动。年平均降水量和年平均气温的变化对苹果种植有积极影响;年平均日照时数的变化对黄土高原南部苹果种植有消极影响,对黄土高原中部和北部有积极影响。从区域尺度上研究最近10年黄土高原苹果主产区的变化格局,可为区域苹果产业政策提供科学依据。
In order to address the relationship between planting area and climatic factors(the average annual precipitation, temperature, and sunshine hours),ArcGIS spatial analysis was used to address for 29 major apple production cities in the Loess Plateau in 2005, 2010, and 2015, so as to quantify the impact of climate factors on regional apple distribution pattern. The results showed that the apple planting areas in the Loess Plateau had mainly shifted to eastern Gansu(Tianshui, Pingliang and Qingyang), central and northern Shaanxi(Yan′an and Yulin), western Shanxi(Linfen and Yuncheng), and westward Henan(Sanmenxia) in the past 10 years;the average annual precipitation and temperature had positive effects on apple planting;average annual sunshine hours had negative effects on apple planting in the southern part of the Loess Plateau, and had positive effects in the central and northern parts of the Loess Plateau. We figured out the change patterns of apple production areas in the Loess Plateau in the past 10 years on a regional scale, which could provide the scientific basis for policy-making on regional apple industry.
