基于Max Ent模型的西南地区传统村落空间格局模拟

Simulation of Spatial Pattern of Traditional Villages in Southwest China Based on MaxEnt Model

传统村落是中华农耕文明和乡土文明的重要载体,是中华传统文化的优秀表现形式。对传统村落的保护以及有机传承能够延续中华民族的文化底蕴,增加国家文化自信,实现乡村振兴。本研究以西南地区的传统村落为研究对象,综合运用MaxEnt模型和地理信息技术,分析影响传统村落空间分布影响因素,模拟西南地区传统村落的潜在分布。研究结果表明,西南地区传统村落空间分布总体呈现东高西低的空间分布特征,最邻近指数R小于1,呈现出空间聚集性。高程、最干月降水量、最暖月最高气温、等温性等是影响传统村落在西南地区分布的主要因子。贵州东南部、云南西北部等是传统村落的高概率分布区,其它地域传统村落的高、中、低概率分布区分布集聚性不显著。

Traditional villages are an important carrier of Chinese agricultural civilization and local civilization,and an excellent form of expression of Chinese traditional culture.The protection and organic inheritance of traditional villages can continue the cultural heritage of the Chinese nation,increase the national cultural self-confidence and achieve rural revitalization.This study takes the traditional villages in Southwest China as the research object,comprehensively uses MaxEnt model and geographic information technology to analyze the influencing factors on the spatial distribution of traditional villages,and simulates the potential distribution of traditional villages in Southwest China.The results show that the spatial distribution of traditional villages in Southwest China is generally characterized by high in the East and low in the west,and the nearest neighbor index R is less than 1,showing spatial aggregation.Elevation,precipitation in the driest month,maximum temperature in the warmest month and isotherm are the main factors affecting the distribution of traditional villages in Southwest China.The southeast of Guizhou and the northwest of Yunnan are the high probability distribution areas of traditional villages,while the high,medium and low probability distribution areas of traditional villages in other regions have no significant agglomeration.
