Abstract

In order to better protect the ecosystem of Hangjia Lake, repair ecological problems, and improve biodiversity, this article takes the ecosystem of Hangjia Lake area as the research object and proposes a geographic information system (GIS)-based ecological restoration planning method under the Internet of Things. The ArcGIS software was used to analyze the rainfall, soil pollution, water pollution, and land use in Hangjiahu area, and evaluate the current status of ecosystem. Moreover, the weight of the influencing factors of ecosystem was calculated. In addition, the ecological restoration was planned from the perspective of optimizing resources and reasonable allocation. Furthermore, Hangjiahu area was planned reasonably based on land suitability and vegetation spatial pattern. The potential and limitation of dense waterway net region of Hangjiahu were analyzed by the multi-factor evaluation method. Finally, the planning was carried out from the aspects of soil and water conservation, biodiversity, and vegetation selection. Experimental results show that the proposed method has good effect on soil and water conservation and many biological species, so it can realize the efficient restoration for the ecosystem in Hangjiahu area.
