中文摘要	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。
英文摘要	This study mainly analyzes some influence factors for the large-scale abandonment of cultivated land in mountainous areas using the method of remote sensing and field investigation. Four counties were selected, including Linzhou city, Yishui, Xundian and Huachi county in the northwest of China. In each county, several sampling areas were selected to identify the abandoned terraces in the mountainous areas by remote sensing interpretation and field research. The geoscience factors of the abandoned terraces in mountainous areas were finally analyzed from the perspective of geosciences. The main results are as follows: 1) Extracted information from terraced field wastes in the sampling area shows that there are varying ratios of the abandoned fields in the four counties. Specifically, the average area rates of the abandoned terraces in the sampling areas of Huachi, Xundian, Yishui county and Linzhou city were 4.11%, 7.68%, 9.46% and 24.03%, respectively; 2) The width of the terraced field was the main factor for the wasteland of terraces. The narrow width of the terraced area was easy to be abandoned according to the relationship between the terraced abandonment rate and the width of terraced fields in Yishui, Linzhou and Xundian. When the terraced width was wide enough, the abandonment rate was not obvious in Huachi county; 3) In rocky mountain areas, the slope of ground and the thickness of the soil layer are the main factors for the width of the terraces. As the slope of the ground increases, the width of the terraces becomes narrow. As the thickness of the soil layer decreases, the width of the terraces becomes narrow. In soil mountainous areas, the slope of the ground was the main factors for the width of terraces, where the width of terraces becomes narrower as the slope increases; 4) The construction of terraces in mountainous areas should consider the local conditions. Most of the newly-built terraces are the so-called unused land from past developments, where the desertification more possibly occurs due to the exhausting natural resource. Therefore, the construction of mountain terraces can mainly refers to the local natural geographical conditions. In the areas with thin soil layers and large slopes, it is not cost-saving to build terraces. This finding can provide a theoretical guidance for the optimization of mountain terraces from the perspective of engineering design.
