Abstract: With the rapid development of mobile Internet, people walk as "sensors" in society to create real-time, actual-environment and large-scale geographic information, especially for the geographic information of regional environments. These information has the characteristics of interaction, real-time, richness and sociality, and becomes gold mine in the eyes of data scientists. Based on the background of "Internet plus" era, with the maturity of mobile Internet, mobile GIS and LBS technology, this paper proposes an intelligent sensing method of ecological environment based on mobile GIS. It develops an APP based on the Android platform, which realizes the functions of querying environmental quality, consulting environmental pollution map, sharing and resolving environmental problems. We sense and obtain Eco-environmental information from the public perspective, provide real-time dynamic environment information querying for the public, and encourage the public to participate in environmental protection. Further, it can provide new method for controlling environmental pollution and obtaining geographic information resources.
