Research hotspots and service pathway evolution in China's urban geology(1995-2024):an analysis based on knowledge mapping and LLM semantic classification
摘要
Abstract
This study systematically investigates the evolution of research hotspots and service pathways in China's urban geology and their interrelationships,based on 2,311 Chinese papers indexed in the China National Knowledge Infrastructure(CNKI)database from 1995 to 2024.Using bibliometric visualization software CiteSpace and a domestic large language model(LLM),the analysis reveals that over the past three decades,urban geological research in China has progressed through four distinct stages:initial exploration,steady growth,smooth development,and high-level expansion.Research hotspots have consistently focused on several key areas,including urban geological work and geological environment,geological hazards and land subsidence,engineering geology and underground space,as well as informatization and outcome services,with different knowledge domains supporting these service pathways with distinct emphases.The integration of emerging technologies such as LLMs has not only enhanced the practical applicability of traditional bibliometric research results but also opened new analytical avenues for urban geological research and related fields.关键词
