摘要
通过GIS定位分析及实地调查采样,研究和分析了钦州市钦南区苏屋村荒废农田的交通条件、灌溉条件、土壤质地、有机质以及速效养分氮、磷、钾基本现状,利用单因子及综合因子评价分析。结果表明,利用单因子评价得出,该区域的3个单元均为N级(不适宜等级),主要制约因子是速效养分钾,其次是磷以及灌溉条件;利用综合因子评价,该区域的3个单元均得86.99分,专家一致认为属于宜耕类。最后依据评价结果针对限制性因子提出建设性建议,并绘出规划图,该研究结果将对钦州市荒废农田的复垦提供理论参考。
By GIS analysis mid filed survey sampling ,the basic situation of tr＇,fffic conditions,irrigation conditions, soil texture, organic matter and N,P, K nutrients of abandoned farmland of Suwu Village of Qinnan District in Qinzhou City were researched and analyzed,and were evaluated and analyzed by using single factor and the comprehensive factors.Results of single factor evaluation showed that three regional units were N level （not suitable） ,and the primary limiting factors was K nutrients,the second limiting factors were P nutrients and irrigation conditions;Results of comprehensive factors evaluation showed that three regional units were 86.99 points ,experts all agreed that belongs to the type suitable for farming. Finally, according to the evaluation results, recommended suggestions to limiting factors were put forward, and a picture vision was drawn, the results would provide the theories basis for Qinzhou City reuse of abandoned farmland.
