Abstract F301.2; 为分析山区梯田撂荒的影响因素,科学指导山区梯田的建设,该研究以位于山区的林州市、沂水县、寻甸县、华池县为研究区,在每个县选取若干采样区,以遥感解译结合实地调研的方式识别出山区撂荒梯田,并从山区梯田工程设计的角度对其撂荒的影响因素进行分析.研究结果表明:1)4个研究区内梯田均呈现出不同程度的撂荒现象,其中华池县、寻甸县、林州市和沂水县的采样区平均撂荒率分别为4.11％、7.68％、24.03％、9.46％;2)梯田的田面宽度是影响山区梯田撂荒的主要因素;3)在以沂水县和林州市为代表的石质山区,地面坡度与土层厚度是制约梯田宽度的主要因素,梯田的宽度随着地面坡度增加而变窄,随着土层厚度的变薄而变窄;在以华池县和寻甸县为代表的土质山区,地面坡度是梯田宽度的主要限制因素.该研究可为山区梯田的优化提出科学理论指导,并为国家相关部门制定政策提供理论依据.
