# Research on the Development of Rural Human Settlement Environment in the Upper Reaches of the Lancang River Based on Ecological Carrying Capacity Constraints

## TL;DR

This study examines how rural settlements in a sensitive ecological area of China can develop sustainably by considering environmental limits.

## Contribution

The study introduces a method to assess rural settlement suitability using ecological footprint analysis and GIS in an ecologically fragile region.

## Key findings

- The total ecological footprint in Nangqen County increased twofold from 2000 to 2020, mainly due to animal husbandry expansion.
- Suitable areas for sustainable rural development and areas requiring protection were identified in Nangqen County.
- The ecological environment remains generally safe, but pressure from human activities is rising.

## Abstract

The development of rural human settlement environments in ecologically sensitive areas, particularly the upper reaches of the Lancang River within the Sanjiangyuan region, has garnered significant attention due to its paramount importance in balancing economic growth and ecological conservation. However, the comprehension of sustainable development strategies within the confines of ecological carrying capacity in these regions remains inadequate. The present study aims to investigate the rural human settlement environment in Nangqen County, situated within the Sanjiangyuan region, and to explore adaptive construction strategies that facilitate harmonious coexistence between human settlements and the natural environment. Utilizing an ecological footprint model integrated with the ArcGIS platform, this research evaluates the ecological carrying capacity and its variations from 2000 to 2020. The results indicate that, despite the land ecological environment being generally safe, the total ecological footprint has surpassed a twofold increase, primarily driven by the expansion of animal husbandry activities. Furthermore, the study conducts a suitability assessment of rural settlements in Nangqen County, pinpointing areas that are most conducive to sustainable development and those that necessitate protection.

This article systematically evaluates the rural human settlement environment in Nangqen County, upper reaches of the Lancang River, considering ecological carrying capacity constraints. Utilizing an ecological footprint model with ArcGIS, the study analyzes changes in ecological footprint, carrying capacity, and pressure from 2000–2020. Suitability assessment of rural settlements identifies areas for sustainable development and protection, proposing strategies to optimize settlement patterns and ensure ecological sustainability.
