    Abstract

    Improving the level of intensive cultivated land use is an important measure to ensure food security and promote the sustainable development of the regional society and economy. Based on data from the statistical yearbook of Maoming City and its counties and districts from 2005 to 2018 and the land use change database of Maoming City for 2018, this study constructed an evaluation index system for four aspects: cultivated land use intensity, cultivated land use degree, cultivated land output benefit and cultivated land sustainable use status. The level of intensive use of cultivated land in Maoming City from 2004 to 2017 was evaluated by AHP, the range method and the comprehensive evaluation model, and its temporal and spatial characteristics were evaluated. The results revealed three major points. (1) The intensive use of cultivated land in Maoming City in the past 14 years was good, and its level showed an overall upward trend, with the intensive use degree of cultivated land rising from 0.4045 in 2004 to 1.3148 in 2017. (2) The levels of intensive use of cultivated land in each county and district of Maoming City were generally on the rise, with no significant differences between them. However, according to the regional distribution, the intensive use level of cultivated land was highest in Maonan District, while it was relatively low in Dianbai County. The largest increase in the level of cultivated land intensive use was in Gaozhou, and the smallest was in Dianbai County. (3) According to the existing problems of cultivated land utilization in Maoming City, combined with the current international and domestic measures to effectively improve the level of intensive use of cultivated land, four suggestions are put forward: to improve the efficiency of cultivated land utilization and effectively protect basic farmland; to improve the overall urban planning and rationally adjust the layout of construction land; to raise farmers’ awareness of the intensive use of cultivated land; and to increase agricultural investment and improve agricultural infrastructure.

    1 Introduction

    In conjunction with the growth of China’s population, the improvement of urbanization and the rapid development of industrialization, the demand for construction land has also been expanding. This expansion has led to the occupation of a large amount of previously cultivated land and a sharp decrease in its total area, which has made China’s scarce cultivated land resources even more constrained, seriously threatening the country’s food security and restricting the continuing sustainable development of the regional society and economy. Therefore, while strictly guaranteeing the quantity of cultivated land, one effective way to ensure China’s future food security is by improving the intensive utilization level of cultivated land. Research on the intensive use of cultivated land originated from the land suitability classification method put forward by the United Nations Food and Agriculture Organization at the 1972 Land Evaluation Conference. Subsequently, scholars at home and abroad have conducted many studies on this issue. These studies have mainly focused on the level and temporal and spatial characteristics of the intensive use of cultivated land (Liu et al., 2017; Liu et al., 2019; Xing et al., 2019; Wu et al., 2020), evaluation methods and models (Ai, 2018; Cao, 2018; Shi et al., 2018), influencing factors and driving forces (Sun et al., 2016; Hou et al., 2017), the relationship with ecological security (Chen et al., 2014), the relationship with urbanization (Deng et al., 2013; Song et al., 2015) and the relationship with carbon emissions (Wang et al., 2014), among others.
