Intermountain basins are the granaries of the karst mountains of southwest China. Revealing the process and trend of land-use transformation in typical mountainous “granaries” is of great significance to optimizing land-use, food security, and rural revitalization in the karst mountains of southwest China. Lianjiang basin in Huishui County is the largest in Guizhou Province of southwest China, and a typical mountainous “granary” is used as a case study area. Based on seven periods of high-definition remote sensing images from 1966 to 2020 and on-the-spot investigation, we adopt the analysis methods of landscape pattern, moving window, and buffer zone and conduct an in-depth study on the spatial evolution of land-use and the land-use transformation law of the typical “granaries” of karst mountainous areas in southwest China from the perspectives of changes in the quantity of land-use, changes in the types of land-use, and changes in the landscape pattern. The results showed that the transformation of land-use in the basin was mainly manifested in the transformation of the function of cultivated land and the diversification of the function of cultivated land. The landscape pattern of the basin was gradually transformed from traditional rural landscape to modern agricultural landscape. The gradient effect of land-use evolution and transformation in the study basin was obvious. Traffic, location, and land resources significantly affect land-use transformation in the basin. Based on the above analysis, this paper proposes that the “granary” basins in karst mountainous areas should optimize the land-use of the basin by the trade-off between regional socio-economic development, ecological protection, and food security. The results of this paper provide a reference for land-use optimization and rural development in the granary-type basins and other similar areas in the karst mountains of southwest China.

“…Some ecologists analyzed influencing factors from aspects such as fertilizers, machinery, pesticides, labor, capital, energy, cultivated land productivity, cultivated land economic benefits, labor productivity, and land use mode transformation and used comprehensive evaluation and multiple regression models to evaluate China's CLIU [30]. The indicators reflected renewable environmental input, nonrenewable environmental input, nonrenewable industrial assistance, renewable organic assistance, agricultural output, and chemical pollution industrial input; the intensive use of farmland was evaluated via energy analysis and the livelihood framework to determine farmers' livelihood types [31]. Comprehensive factors reflected the levels of material productivity, the implicit flow of material output and stock, and the effects of environmental economics.…”

Cultivated land intensive utilization (CLIU) exhibits spatial heterogeneity that is influenced by both natural and anthropogenic factors, with land dissected into different scale systems; however, CLIU has not yet been systematically explored. This study takes the Beibu Gulf urban agglomeration, a national-level model area for integrated land and sea development in China, as an example to investigate the spatial heterogeneity of CLIU and explore its driving factors through multiple econometrical and geographical methods, including identifying its underlying mechanisms. The results indicate that (1) the CLIU index is 0.334, its Gini coefficient is 0.183, and its comprehensive level has a low intensity and obvious spatial nonequilibrium characteristics. Hypervariable density (50.33%) and the intraprovincial gap (45.6%) are the main sources. (2) Among the independent effects of single factors, the multiple cropping index (0.57), labor force index (0.489), and intensification of construction land (0.375) exert the most influence on CLIU spatial variation. The interaction effects of two factors primarily manifested as nonlinear enhancements, with the interaction between the labor force index and multiple cropping index being particularly noteworthy (0.859). (3) The geographically weighted regression coefficients reveal that temperature (0.332), multiple cropping index (0.211), and labor force index (0.209) have relatively large and positive impacts on CLIU, while slope (−0.1), precipitation (−0.087), and population urbanization (−0.039) have relatively small and negative impacts; all factors exhibit spatial nonstationarity. The spatial heterogeneity of CLIU in the Beibu Gulf urban agglomeration is characterized by patterns’ nonequilibrium and factors’ nonstationarity. The driving mode of multiple factors on CLIU is manifested as follows: natural factors of cropland utilization provide basic guarantees, internal factors of CLIU provide positive enhancement, and external factors of land intensive utilization provide auxiliary promotion.

“…In the vast developing countries with economic construction as the main task, cultivated land utilization efficiency mainly pursues the two-dimensional unification of resources and social economy. Previous studies have paid too much attention to the increase of cultivated land social and economic output generated by cultivated land input [24][25][26][27]. With the continuous increase of the population, the continuous depletion of resources, and the excessive use of chemical fertilizers, pesticides, agricultural films, and other agricultural chemicals, the ecological environment has deteriorated, and the ecological environmental benefits have gradually attracted widespread attention from scholars [28][29][30][31].…”

Cultivated land is the foundation of human existence and development. Eco-efficiency of Cultivated Land Use (ECLU) is a comprehensive index to measure the economic, social, and ecological output of cultivated land. Therefore, it is of great theoretical and practical significance to describe the evolution characteristics of ECLU, and to explore the improvement path of ECLU for realizing the sustainable utilization of cultivated land resources, coping with the food crisis, and alleviating global warming. Hubei Province, as a traditional major province of grain production in China, can provide a reference for other developing countries in the world in terms of its management experience and technology in the production and utilization of cultivated land. In this study, the carbon emissions and pollution emissions of cultivated land use were incorporated into the calculation system of ECLU. Firstly, the undesired super-efficiency Slack-Based Measure (SBM) model was used to calculate ECLU in Hubei Province from 2008 to 2020. Secondly, the Exploring Space Date Analysis (ESDA) method was used to characterize its temporal and spatial evolution characteristics. Finally, the improvement direction of ECLU in the future was proposed from the perspective of cultivated land input factors. The research shows that, first of all, from 2008 to 2020, ECLU in Hubei Province showed a fluctuating growth trend, rising from 0.457 to 0.521, during which, it experienced two “U”-shaped changes, in 2011 and 2016. Secondly, the spatial agglomeration effect of ECLU in Hubei Province continued to increase, mainly showing two agglomeration patterns of high–high and low–low. Finally, ECLU in the study area was significantly negatively correlated with the redundancy rate of input factors. There was a redundancy in the input factors of cultivated land production, among which, the redundancy degree of agricultural employees (AM), chemical fertilizer usage (CFU), and total power of agricultural machinery (AMP) were more serious. Based on this, this paper proposes to adhere to the principle of adapting measures to local conditions and progress in an orderly manner, and to formulate differentiated and phased policies for improving ECLU according to natural resource endowments, and social and economic development conditions in different regions, in order to achieve the coordinated and sustainable development of people and cultivated land.
