基于 ArcEngine 的城市绿地生态功能动态评估系统的设计与实现

摘要

当前我国在城市绿地生态系统功能评估方面的研究方兴未艾，本研究主要将城市绿地生态功能的主要模型予以实现，可以在不同时间、不同季节条件下，针对居民对城市绿地需求的不同特征，选择适当的基于气象因素的绿地生态功能质量动态评估，本研究以哈尔滨市作为研究城市，采集哈尔滨市绿地数据，选择涉及绿地涵养水源、固碳释氧、休闲游憩、降低噪声、净化大气五个方面的生态服务评估模型，并简要阐述系统设计与实现的方法。%Our current research in urban greenland ecosystem function evaluation is in the ascendant , and this paper mainly makes the model of urban greenland ecological function to be implemented .The demand of residents for urban greenland changes according to the condition , such as time, season, and weather condition .People could choose the proper model from various model of ecological function quality dynamic assessment about greenland .This paper selects Harbin city as re-search region , collects Harbin greenland data from RS images , and selects evaluation model involving five aspects include water-source conservation , carbon fixation and oxygen release , leisure and recreation , noise reduction , and purifying at-mosphere .This paper also concerns design and implementation method of dynamic evaluation system of the ecological func -tion about urban greenland .
