The development and protection of ecological corridors to connect green natural features has been recognized as an effective means for improving the resilience of cities. It is especially important for the cities which are in the rapid urbanizing process. In this paper, we used high-resolution spatial data to extract the distribution of ecological corridors by using the Least Cost Path model for the city of Taiyuan, China. Then, a prediction of the urban area for the year 2035 was achieved by using the SLEUTH model. Finally, we analyzed the negative impact of urban expansion on the corridors under current urbanization trends. Our results show that the regional corridors are mostly distributed in the western mountainous area, connecting large natural areas. There are also three ecological corridors crossing the city from the east to west. According to our prediction, Taiyuan will mainly grow southward along the urban edge and road network. As a result, two ecological corridors in the central and southern parts of Taiyuan will be largely occupied, especially the corridors in Xiaodian district which account for 72.51% of the total occupied corridor area. To avoid further conflict, the urbanization intensity along the sides of the corridors should be restricted to maintain corridors of a certain width. Our research findings can provide urban planners insightful suggestions for conservation and restoration of ecological networks and assist in spatial planning.

Coupling relationship among scale parameter, segmentation accuracy, and classification accuracy in GeOBIA / Ming Dongping in Photogrammetric Engineering & Remote Sensing, PERS, vol 84 n° 11 (November 2018)

It is crucial to make it clear which one of these two measures is more important and what is the coupling relationship among segmentation scale parameter, image segmentation and classification accuracy. This paper employs series of segmentation and classification to show that (1) intrasegment homogeneity is more important than intersegment heterogeneity in GeOBIA; there is always highly positive correlation between intrasegment homogeneity and classification accuracy; (2) with the increase of spectral heterogeneity parameter, both image object amount and the intrasegment homogeneity decrease; however the intersegment heterogeneity increases or increases first then decrease after the appropriate scale; and (3) the appropriate scale means there is a compromise between intrasegment homogeneity and intersegment heterogeneity. The research findings are helpful to raise awareness among practitioners who suffer from scale issues in GeOBIA.
