摘要

目的为探究峰丛洼地石漠化区乡村聚落的形态学特征及空间演变规律。方法基于PLUS模型预测2035年经济发展情景、自然发展情景和生态保护情景下的乡村聚落分布，利用形态学空间格局分析(MSPA)方法识别乡村聚落的形态学特征，采用景观格局指数、景观综合动态度和Ripley K函数方法，实现对乡村聚落过去-现在-未来的形态学特征及空间演变规律分析。结果1) 1990—2022年乡村聚落面积呈上升趋势，面积增加6.09 km2，数量由366增加至1 253。核心与边缘是研究区内的优势乡村聚落类型，其面积分别增加1.90、1.51 km2，主要分布在研究区中部，孤岛和分支等主要分布在北部和东北部，其面积分别增加1.07、1.15 km2。2)乡村聚落类型的复杂性、丰富程度和破碎化程度整体上呈增加趋势；乡村聚落类型1990—2000年发育最为平缓，2010—2022年发育最为剧烈，乡村聚落类型扩张主要发生在兴街村和老街村及周边地区；乡村聚落类型在研究尺度内都表现出集聚趋势，随着空间尺度的增加乡村聚落空间分布的聚集特征减弱且城镇化过程空间尺度缩小。3)3种情景下，乡村聚落面积均呈上升趋势，其面积分别为11.42、7.68、9.14 km2；核心是研究区内绝对优势类型，其面积分别增加4.02、2.60、3.14 km2，乡村聚落类型在空间尺度上呈集聚分布，并且生态保护情景抑制乡村聚落的扩张。结论研究区乡村聚落处于快速发展阶段，乡村聚落的扩张主要表现在核心扩张上，而孤岛的扩张则是加剧乡村聚落空间分布的复杂性，并且城镇化过程中乡村聚落逐渐聚集在较小的空间尺度。

Abstract

ObjectiveTo explore the morphological characteristics and spatial evolution patterns of rural settlements in the karst depression rocky desertification area.MethodsThe distribution of rural settlements under the scenarios of economic development

natural development

and ecological protection by 2035 was predicted using the PLUS model. The morphological characteristics of rural settlements were identified through Morphological Spatial Pattern Analysis (MSPA)

while the past

present

and future morphological characteristics and spatial evolution patterns of rural settlements were analyzed using landscape pattern indices

landscape comprehensive dynamics

and the Ripley K function method.Results1) There was an increasing trend in the area of rural settlements from 1990 to 2022

with the area expanding by 6.09 km2 and the number of settlements increasing from 366 to 1 253. The core and edge were identified as the dominant types of rural settlements in the study area

with their areas increasing by 1.90 and 1.51 km2

respectively

primarily concentrated in the central part of the study area. In contrast

isolated patches and branches

which increased by 1.07 and 1.15 km2 respectively

were mainly distributed in the northern and northeastern parts. 2) The complexity

richness

and fragmentation of rural settlement types generally showed an increasing trend. The development of rural settlement types was most gradual from 1990 to 2000 and most intense from 2010 to 2022

with the expansion primarily occurring in Xingjie Village

Laojie Village

and their surrounding areas. Across the study scale

rural settlement types exhibited a clustering trend

which weakened as the spatial scale increased

and the urbanization process led to a reduction at spatial scale. 3) Under all three scenarios

the area of rural settlements showed an increasing trend

with the areas reaching 11.42

7.68 and 9.14 km2

respectively. The core type was identified as the dominant type in the study area

with its area increasing by 4.02

2.60 and 3.14 km2

respectively. Rural settlement types exhibited a clustering distribution pattern across spatial scales

with the ecological protection scenario restricting the expansion of rural settlements.ConclusionRural settlements in the study area are in a rapid development stage

with expansion mainly occurring in the core areas. The expansion of isolated patches has increased the complexity of the spatial distribution of rural settlements

and during the urbanization process

rural settlements have gradually concentrated within smaller spatial scales.
