摘要/Abstract

摘要： 针对创意产业园区的分布特征构建创意产业的生态位模型，选取与城市环境有关的23个因子，通过最大熵模型(MaxEnt)确定每个因子的贡献度，从中筛选出对创意产业分布做出主要贡献的8个环境因子.以模糊隶属度研判城市环境因子对创意产业的作用，并与环境因子的权重相结合，得到研究案例区创意产业的适宜度，据此生成创意产业适宜度预测图.应用GIS空间分析的方法，依据城市环境适合创意产业发展的程度，将城市划分为不适宜区、一般适宜区、次适宜区和最适宜区四类区域.研究结果显示，创意产业最适宜区主要集中在东部沿海城市和省会城市，并且预测结果与实际现状相近，模型可靠性较高.

关键词: 创意产业, 适宜度, 最大熵模型(MaxEnt), 模糊隶属度

Abstract: An ecological niche model of creative industry was developed on the basis of the geographic characteristics of creative industry parks and 23 factors associated with the environment of cities were selected. The maximum entropy model (MaxEnt) was applied to determine the contribution of each factor and identify 8 major contributing factors. The fuzzy membership was applied to study the effect of environmental factors on the creative industry. The model results were integrated with the weight of environmental factors to get the suitability of creative industry and to produce predictive maps of site suitability. Then， based on the GIS spatial analysis， the cities were categorized into four zones， including unsuitable， low-suitable， moderatly-suitable， and highly-suitable regions， whose suitability ranges from low to high. The results showed that highly-suitable regions are mostly located in the eastern coastal provinces and provincial cities in China and that the predicted results are similar to the actual ones， which confirms the high reliability of the model.

Key words: creative industry, suitability, the maximum entropy model (MaxEnt), fuzzy membership
