摘　　要：[目的]山地区地形条件复杂,耕地资源紧缺,耕地利用限制性因素多。对山地区耕地利用和保护的相关问题进行研究,有助于推动山地区更好地利用与保护耕地。[方法]以湖南省永顺县为例,对耕地的组成及特征、利用现状进行分析,总结存在的问题。[结果]永顺县耕地特征为:组成以水田为主,整体坡度大,空间分布差异明显。利用特征为:数量总体保持增长,水田数量减少,旱地数量增加,"非耕化"情况普遍。耕地利用与保护存在的问题为:本底质量差、利用效益低,利用耕地发展林果业现象普遍,耕地生态安全不容忽视,高标准农田建设工程建设内容有待加强。[结论]山地区自然资源部门应主动介入农业结构调整,合理引导;应根据实际限制因素,以提高耕地本底质量为基础,努力提高利用水平和经济效益;加强耕地生态保护,重视过多施用化肥、依靠化学农药的问题,推广绿色化耕地利用方式;完善高标准农田建设内容,全面促进耕地质量提升。针对各地存在的具体问题,进行系统有效的制度与政策设计,全面加强耕地的科学合理利用和有效保护。[Objective]The terrain conditions in mountainous areas are complex,the arable land resources are scarce,and there are many restrictive factors for arable land use.Research on issues related to the use and protection of cultivated land in mountain areas can help promote the better use and protection of cultivated land in mountain areas.[Method]Taking Yongshun County in Hunan Province as an example,the composition,characteristics and current status of cultivated land were analyzed,and the existing problems were summarized and analyzed.[Result]The characteristics of cultivated land in Yongshun County are:The composition is mainly paddy field,the overall slope is large,and the spatial distribution difference is obvious.The utilization characteristics are as follows:the number keeps increasing on the whole,the number of paddy fields decreases,the number of dry land increases,and the situation of“non-cultivation”is common.The problems with the use and protection of cultivated land are:poor background quality,low utilization efficiency,widespread use of cultivated land to develop forestry and fruit industries,ecological safety of cultivated land cannot be ignored,and the construction content of high-standard farmland construction projects needs to be strengthened.[Conclusion]The natural resources department in the mountain area should take the initiative to participate in the adjustment of agricultural structure and reasonably guide;based on the actual limiting factors,on the basis of improving the background quality of cultivated land,strive to improve the level of utilization and economic benefits;strengthen the ecological protection of cultivated land,pay attention to the problem of excessive application of chemical fertilizers and rely on chemical pesticides,promote the use of green cultivated land;improve the content of high-standard farmland construction,and comprehensively promote the improvement of cultivated land quality.Aiming at the specific problems existing in various places,systematic and effective sys
