Cultivated land quality was assessed by BP neural network in Dazu County, Chongqing. The assessment results showed that paddy lands were mainly of the second-grade and third-grade, while dry lands were mainly of the first-grade and second-grade. It illustrated the high natural quality of the cultivated land, but the natural quality only reflected land natural characteristics. Therefore, influence coefficient was used to modify natural quality index based on the investigation to households. At the same time, by using the household income as the value of cultivated land, the impact of natural quality and investment structure on the value were further discussed. The results showed that trinomial equation and binomial equation were fitted to reflect the relationship between natural quality and income.

该文采用BP神经网络模型对重庆市大足县耕地自然质量进行评价，发现研究区水田自然质量等级以二等地和三等地为主，旱地以一等地和二等地为主，耕地自然质量总体偏高；但耕地自然质量仅仅是耕地自然属性的反映，因此在基于对研究区农户行为调查的基础上，采用"影响力系数"对耕地自然质量进行修正，并将农户收益作为耕地质量货币化价值的表现，进一步讨论了耕地自然质量和农户投资结构对这种价值的影响以反映对耕地质量的影响。

Analysis of the archives data of Hetian region during the Republic of China showed that this time water resources basically maintained on a stable level, and it was not the decisive factor to the waste of local big area tilth, but the essential factor actually restricted the population quantity, the reclamation wasteland scale and the overall cultivated area level in all the counties.

地区人口增长过多引发对地区耕地面积的需求扩大，同时引起对耕地灌溉水量的增长需求扩大，由此呈现出农田灌溉水不足的表象，造成地区人口、耕地水平与水资源承载力相互关系的失调；即影响和田地区耕地撂荒的关键是当地水资源总量与人口规模、耕地面积总水平的平衡关系，突破这个平衡就必然引起耕地的撂荒或生态环境劣化；而诱发耕地大面积撂荒的自然因素也与过度垦荒有一定程度的关系。
