[Spatial analysis on land use in Xishuangbanna].

Area of Science:

• Environmental Science
• Geography
• Remote Sensing

Background:

• Land use systems are complex and influenced by various environmental factors.
• Understanding these relationships is crucial for sustainable land management.
• Xishuangbanna presents a unique case study due to its diverse topography and land cover.

Purpose of the Study:

• To analyze the relationship between land use and topographic factors (elevation, slope, river systems) in Xishuangbanna.
• To identify the dominant land use types and their spatial distribution.
• To understand the impact of human activity and proximity to water on land use patterns.

Main Methods:

• Remote sensing and Geographic Information System (GIS) technology were employed.
• Analysis of topographic factors including elevation, slope, and river systems.
• Spatial analysis of land use types and their correlation with environmental variables.

Main Results:

• Forestland (74%), cropland (13%), and grassland (18%) dominate Xishuangbanna's land use.
• Land use types exhibit a single-peaked curve distribution with elevation.
• Cropland and urban land, influenced by human activity, show lower slope indices.
• Proximity to river systems strongly influences land use, with human-dominated uses near water.

Conclusions:

• Topographic factors significantly shape land use patterns in Xishuangbanna.
• A distinct spatial zonation of land use exists relative to elevation and river proximity.
• The study highlights a landscape structure with forestland as the matrix, rivers as corridors, and cropland as patches.
