为进一步优化利用及保护现有的耕地资源,推动地区经济和自然生态稳定发展,该文围绕耕地资源展开讨论。基于对耕地资源及耕地时空变化的概念叙述,从耕地总量及人均占有量的角度分析时空变化特点,重点探讨引起耕地资源变化的因素,研究各项值影响因子的相关程度,并提出更好保护耕地资源的举措,发挥资源本身的多重效益。

In order to further optimize the utilization and protection of existing cultivated land resources and promote the stable development of regional economy and natural ecology, this paper focuses on cultivated land resources. Based on the concept description of cultivated land resources and spatio-temporal change of cultivated land, this paper analyzes the characteristics of spatio-temporal change from the perspective of total cultivated land and per capita occupancy, focuses on the factors causing the change of cultivated land resources, studies the correlation degree of various value influencing factors, and puts forward measures to protect cultivated land resources and give full play to the multiple benefits of resources themselves.
