| Terrain |
X1 |
Elevation |
There is an abundance of cultivated land in flat regions, making development relatively straightforward; however, development in high-altitude areas poses significant challenges |
| X2 |
Slope |
The steep slope complicates mechanization, reduces agricultural production efficiency, and increases the likelihood of cultivated land being abandoned or repurposed for other uses |
| X3 |
Aspect |
Slope orientation affects the growth cycle of crops and, consequently, influences agricultural yields. Low agricultural efficiency may prompt the conversion of land to alternative uses |
| Transport |
X4 |
Highway mileage |
Convenient transportation will enhance population mobility and stimulate economic development, resulting in the utilization of cultivated land |
| Climate |
X5 |
Average temperature |
Crops require the appropriate temperature for optimal growth, which in turn affects agricultural yields. Low agricultural efficiency may lead to the conversion of farmland for alternative uses |
| X6 |
Precipitation |
Precipitation is essential for crop growth and significantly impacts agricultural yields |
| X7 |
Average relative humidity |
Humidity significantly affects crop growth, which in turn impacts agricultural yields |
| X8 |
Sunshine duration |
Sufficient sunlight is a key factor in determining crop growth trends, which in turn influences agricultural yields |
| Economy |
X9 |
Gross regional product |
An important indicator of social and economic development is the conversion of cultivated land into industrial, commercial, and urban construction land |
| X10 |
Primary industry |
Agriculture (planting, forestry, animal husbandry, fishing, etc.) directly demonstrates the utilization patterns of cultivated land |
| X11 |
Secondary industry |
Industry (extractive, manufacturing, etc.) Manufacturing, production and supply of electricity, gas and water) and construction, will directly impact cultivated land |
| X12 |
Tertiary industry |
Other industries, aside from primary and secondary sectors, will directly occupy cultivated land |
| X16 |
Proportion |
An important indicator of the level of urbanization is the migration of the rural population to cities |
| Population |
X13 |
Total resident population |
The change in population size exerts pressure on land resources |
| X14 |
Rural population |
The decline in the rural population may result in the abandonment of cultivated land, which can subsequently be repurposed for non-agricultural purposes |
| X15 |
Urban population |
The growth of the urban population will lead to an expansion of urban development, encroaching upon cultivated land |
| X17 |
Population density |
Population density influences the distribution of the rural labor force and the intensity of land use |
