With the intensification of urbanization and agricultural scale, natural watersheds have been damaged, and the ecological environment faces serious threats. Therefore, the open-source software InVEST was used to assess the habitat quality in the Dianshan Lake area in 2015 and 2022. The results showed that urbanization and agricultural expansion had a significant impact on the ecosystem, leading to an overall decline in habitat quality in Dianshan Lake. According to different threat factors and degradation degree, five landscape optimization strategies are summarized and conducted landscape design renovation along the upstream coast of the Liu River as an example, In general, the adopted ecological model assessment method provides the spatial and temporal distribution information of habitat quality in Dianshan Lake area, and provides reference significance for decision makers with case design, which is helpful to improve urban planning and development to improve habitat conservation along the urban rivers.
