淮北市杜集区耕地质量等级评价及提升措施

Grade Evaluation of Cultivated Land Quality in Duji District, Huaibei City and ItsImprovement Measures

为掌握杜集区耕地质量等级与高、中、低产田在各乡镇的分布,探究杜集区耕地质量等级提升的有效措施,本文利用ArcGIS软件平台、县域耕地资源管理信息系统平台,通过构建评价指标体系、确定评价单元、确定评价指标权重和隶属度,建立耕地质量评价数据库,完成杜集区的耕地质量等级划分。结果表明,杜集区平均耕地质量等级为4.58级,高产田主要分布在朔里镇、石台镇和段园镇,面积1 547.93 hm^(2),占全区耕地总面积的19.34%;中产田分布范围较广,包括矿山集街道、朔里镇、高岳街道、段园镇和石台镇,面积6 455.68 hm^(2),占全区耕地总面积的80.66%。依据杜集区耕地质量等级评价的结果,初步判断杜集区耕地质量等级提升的限制因素为灌溉能力和排水能力,提出了相应的耕地质量提升措施,并分析了耕地质量提升模式及其取得的成效。

In order to grasp the cultivated land quality grade and the distribution of high,middle and low yield farmlands in each township,and explore the effective measures to improve the cultivated land quality grade in Duji District,this paper established the cultivated land quality evaluation database and completed the classification of cultivated land quality grade in Duji District by using ArcGIS software platform and county cultivated land resources management information system platform to build the evaluation index system,determine the evaluation unit,determine the weight and membership degree of evaluation indexes.The results showed that the average cultivated land quality grade in Duji District was 4.58,and the high yield farmland was mainly distributed in Shuoli Town,Shitai Town and Duanyuan Town,with an area of 1547.93 hm^(2),accounting for 19.34%of the total cultivated land area in Duji District.The middle yield farmland was widely distributed in Kuangshanji Sub-district,Shuoli Town,Gaoyue Sub-district,Duanyuan Town and Shitai Town,with an area of 6455.68 hm^(2),accounting for 80.66%of the total cultivated land area in Duji District.According to the evaluation results of cultivated land quality grade in Duji District,it was preliminarily judged that the factors limiting the improvement of cultivated land quality grade in Duji District were irrigation capacity and drainage capacity,and the corresponding measures to improve the cultivated land quality were put forward,and the improvement mode of cultivated land quality and its achievements were analyzed.
