Abstract: Abstract: Land normally serves as the carrier of urban and suburban districts in the spatial planning and development strategies. There is a great impact of land use structure on the habitat quality of urban suburbs in recent years. Taking the suburb of Wuqing District, Tianjin, China, as the research area, this study aims to evaluate the sustainable development of land use and habitat quality at the metropolis suburb. The data of land use was collected from 1980-2018. An InVEST model was used to determine the measure level of the habitat quality module. A numerical analysis was made in the habitat quality module to explore the change of land use transfer and land use dynamic degree in the key timeline. An attempt was made to clarify the integrated habitat degradation degree with land use and the evolution of habitat quality structure at the Beijing-Tianjin metropolitan suburb. A relationship model was established for the habitat quality and the spatiotemporal evolution of land use. The results showed that: (1) The type of land use in Wuqing District was dominated by the cultivated land during 1980-2018. Specifically, the area of farmland and unused land decreased significantly, whereas, the area of urban land and rural settlements increased rapidly. There was a relatively small proportion of woodland and grassland. (2) In land-use type transfer, there was the largest transfer area of cultivated land, followed by that of urban and rural residential land. The woodland and grassland shifted to the urban and rural residential land, whereas, the water area to the cultivated land. The unused land changed most. (3) In comprehensive land use dynamic degree (CLUDD), there was an increase in the change rate of land use for the urban land, rural residential land, and water areas, as well as a decrease in that of cultivated land. (4) There was a trend of "urban expansion and farmland contraction", and "human advancing and grass retreating", but in some years there was also a transition of "grass and water advancing". The habitat quality in Wuqing District was in the middle grade, but the area of the middle grade tended to decrease. There was an increase in the area of the low-grade habitat quality, whereas, a downward trend in that of lower grade, while that of the higher and the highest grade tended to expand. The finding can contribute to the precise implementation of the protection strategy of habitat quality and of "ecological civilization", especially for land planning in trans-regional metropolitan areas ,further promoting new urbanization in China.
