Construction of Ecological and Recreation Patterns in Rural Landscape Space: A Case Study of the Dujiangyan Irrigation District in Chengdu, China

The rapid expansion of urbanization has promoted the prosperity economy and society but also caused rural ecological problems. This study takes Dujiangyan Irrigation District as an example, to construct recreation patterns, it breaks through pattern construction mode using a single factor that been used in previous studies. We analyzed impact landscape connectivity area thresholds at different scales on selection source areas, integrated urban human disturbance factors into resistance surface construction. Finally, comprehensive network combining “ecology recreation” was determined minimum cumulative model. Multiscale analysis threshold setting greatly results identification. After optimization, we identified four corridors twenty-seven recreational corridors, regional security significantly improved compared with upper planning content. Therefore, this provides reference for long-term significance spatial protection utilization rapidly urbanizing areas.
