Jiangxi: region in China
What exactly constitutes the spatial extent of the city? For these aggregations, we used the Global Human Settlement Layer Urban Center Database (GHS-UCDB) to define the boundaries of the city. These cities -- or urban centers -- cover areas that are densely populated and built-up, and so may extend beyond the spatial borders of these cities that we may be familiar with. The GHS area is shaded in blue.

Most recent snapshot: Taking into account the entire (i.e. aggregate) street network in Jiangxi as of 2014, the overall level of street-network sprawl is 3.31, which is highly disconnected.
Trends in street network construction: The SNDis of street construction for the respective time periods are 3.14, 4.05, 3.22 and 2.79. Street construction in Jiangxi increased in disconnectivity initially but has since improved. The streets constructed in 1976-1990 were the most disconnected.
Quantity of street network construction: The street network in Jiangxi spans a total of 71068 kilometers. The period with the greatest volume of street construction was 2001-2014. These roads have an SNDi of 2.79, which is in the 40th to 60th percentile of disconnectedness.
Effect on the aggregate network: New construction in each period adds to the total stock of streets, but does not change streets that have already been built. Therefore, it has a limited effect on the street network as a whole. The SNDis of the aggregate street network in the respective time periods are 3.14, 3.66, 3.62 and 3.31. The aggregate street network in Jiangxi increased in disconnectivity initially,but the trend has turned around after 1990.
The level of street-network sprawl in new development in Jiangxi peaked in 1976-1990. To get a sense of how street development has changed in Jiangxi, we can consider three of its most populous cities: Nanchang, Ganzhou and Jiujiang. Out of the three cities, Nanchang and Jiujiang do not follow the same trend as the region. The level of street-network sprawl in new development in Nanchang followed a zig-zag trend with an overall increase. The level of street-network sprawl in new development in Jiujiang followed a zig-zag trend with an overall decrease.
