【2】D
【3】C
【解析】
试题分析
【1】根据材料可知,由于主观原因放弃耕种的耕地,由于农业效益较低,农村劳动力大量转移,种植业劳动力短缺,故导致农村耕地撂荒,故主要原因是农村劳动力缺乏,D项正确;其他说法不合题意,故排除。
【2】农村耕地撂荒,会导致没有人区从事种植业,这既是一个经济问题,也是一个社会问题,将会影响粮食生产安全。农村社会稳定和推进农业现代化和实施城乡统筹的进程,故D项对;耕地长期撂荒,缺少管理,保水保肥能力差,耕地肥力会下降,故B错;农村经济效益低下,故导致农村劳动力大量外出,故A项错误。
【3】从针对撂荒出现的原因分析,因地制宜。禁止民工外出打工,短期内不现实,故A项错误;稳定农产品的价格,不能根本上解决,故B项错误;统一管理撂荒耕地,可以统一处理对土地的使用,故C项正确;加强农田水利建设,对撂荒没有帮助,故D项错误。
