Abstract
The high-resolution regional division of mountainous area types has important scientific significance for promoting precise management of land space and regional sustainable development. At present, the classification method of mountainous area types is mainly at the county level and above, while classifications for towns and villages are nearly nonexistent, which poses a technical challenge for rural revitalization and the construction of ecological civilization in mountainous areas. We used Yuxi city, Yunnan Province, as the target area of this research, which was based on GIS technology and Digital Elevation Model (DEM) data and socioeconomic environmental monitoring data. The most appropriate statistical unit (e.g., 2.8224 km2) for topographic relief was defined, and the study area was divided into six mountain types: flatlands, hills, low mountains, medium-low mountains, midmountains, and subhigh mountains. Based on the township scale, an index system and classification method dominated by the plain comprehensive index were established to carry out mountain area classifications at township scales. The 75 towns of Yuxi city can be classified into 27 plain towns, 23 mountain-plain towns, and 25 mountain towns from an empirical application perspective, which can provide strong data support and a reference basis for studying the evolution characteristics of land use in different geographical spaces and their interrelationships as well as differentiated land space planning and governance.
Highlights
As important regions that support water, energy, and biological diversity on earth [1], mountains occupy 24% of the global land surface area, provide homes for 12% of the world’s population, indirectly offer goods and services for more than 40% of the global population, and play a very important role in the survival and development of humans [2, 3]
With the rapid development of cities, which are the main study areas of human-earth relations [14, 15], mountainous areas have gradually become marginal areas and problem areas for Complexity economic development [16, 17] due to the fragility of mountain ecosystems and excessive human activity, soil erosion, deterioration of the ecological environment, economic backwardness, population poverty, and other problems [18,19,20]. e scientific definition of mountains and mountainous area types can provide a basis for classified development and classified policy, which are conducive to promoting the construction of ecological civilization and sustainable development in mountainous areas
Areas up to 1,500–2,000 m sea level account for 49.15% of the city and form nearly half of the entire research area. rough slope analysis, it was found that the average slope is 21° and that mountains are widely distributed. e highest relief degree of the land surface (RDLS) is 1,335 m, with little overall undulation, but local undulation is great. erefore, in the classification of mountainous area types at the township scale, RDLS should be considered as an important index and be combined with altitude and slope to classify mountain types
Summary
As important regions that support water, energy, and biological diversity on earth [1], mountains occupy 24% of the global land surface area, provide homes for 12% of the world’s population, indirectly offer goods and services for more than 40% of the global population, and play a very important role in the survival and development of humans [2, 3]. Mountainous areas emphasize regional combinations of humanity and geomorphology [11, 12] and interactions between humans and the geographical environment which is the research carrier for exploring the relationship between humans, land, and sustainable development [13]. With the rapid development of cities, which are the main study areas of human-earth relations [14, 15], mountainous areas have gradually become marginal areas and problem areas for Complexity economic development [16, 17] due to the fragility of mountain ecosystems and excessive human activity, soil erosion, deterioration of the ecological environment, economic backwardness, population poverty, and other problems [18,19,20].
