Landscape metrics for land use/cover change and green space pattern in Can Tho city in 1998-2020 based on remote sensing and GIS

Changes in land cover/green space in Can Tho city in the period 1998-2020 were analyzed based on remote sensing data and the perspective of landscape ecology. The data collected from JAXA on land cover/land use classification entire Can Tho city in the period 1998-2020 was used to extract landscape metrics and to analyze the changes by a conversion matrix. The result shows a complex change in the urban green space in the period 1998 - 2020 in Can Tho. Research results show that Can Tho city had rice paddies and other croplands accounting for the majority of the land use structure. In the period 1998-2020, the city experienced a major shrinkage in croplands. Although other land use/cover types fluctuated differently, the fragmentation process still prevailed with fragments having discrete connections in space. The process of urbanization occurred with the expansion of built-up, but the concentration level was not high, with small fragments appearing sporadically distributed. However, comparing the landscape indices in the period 1998 – 2020 showed the aggregation process was increasingly taking place, and the level of fragmentation had tended to decrease. This trend was evidenced by the sharp increase in the number of patches, effective mesh size, and splitting index simultaneously with the gradual decline of the LPI index. The research results show high potential in expanding green space in Can Tho as well as application in planning urban green space development.
