江苏高邮鲜食葡萄栽培生态适宜性区划

The ecological regionalization of table grape cultivation in Gaoyou,Jiangsu province

为促进高邮市鲜食葡萄观光产业持续健康发展,有效提高经济效益和生态效益,利用江苏省1981—2019年67个气象站资料、土壤属性及基础地理信息数据,根据鲜食葡萄露天栽培生长对气象等生态条件的需求,提出7—9月降水量、日照时数及土壤类型为葡萄栽培生态适宜性区划指标。基于ArcGIS的空间插值计算及自然断点法将高邮市葡萄栽培生态适宜性细分为适宜、较适宜两个等级。结果表明,高邮市鲜食葡萄生长所需的热量和水分资源充足,而土壤条件欠佳。其中,适宜区主要位于高邮市南部和东部的部分乡镇,生态资源配置相对较好,较适宜区位于中北部大部分地区,土壤条件略差。在本地葡萄栽培生态适宜性评估中土壤特征起主导作用,明确指出加强田间土壤改良和管理是确保高邮地区葡萄品质优良的关键。

In order to promote the sustainable and healthy development of grape tourism industry in Gaoyou city,and improve economic benefit and ecological benefit,this paper analyzes the data of 67 meteorological stations and soil data from 1981 to 2019 in Jiangsu province,according to requirements of meteorological and ecological conditions for table grape cultivation in open pit,the precipitation,sunshine hours and soil types from July to September were applied for the ecological suitability zoning of table grape cultivation in the open pit. The ecological suitability of grape cultivation was divided into two grades using the spatial interpolation and natural breakpoint method of ArcGIS in Gaoyou city. The results showed that the heat and water requirements of table grape growth in Gaoyou city were sufficient,and the soil conditions were not good;the ecological suitable areas were mainly located in some towns in the south and east of Gaoyou city,and the most areas in the north and the middle of Gaoyou city were more suitable areas.In this paper,the soil types play an important role in evaluating the ecological suitability of grape cultivation,strengthening soil improvement and management is stated clearly to ensure the quality of grape in Gaoyou city.
