Land-use/cover change (LUCC) caused by urbanization has impacted environment and become an important factor driving global change. Karst is a very fragile environment and the LUCC can cause massive change of the environment. An integrated approach was used to explore the environmental effect of LUCC with urbanization and China's ecosystem restoration projects during the period 1996–2010. The results show that the area dedicated to arable land, grassland, water area, and unused land have declined by 243.04 km², 22.96 km², 2.06 km² and 13.61 km², whereas the size of forestland and construction land have increased by 153.85 km² and 127.82 km², respectively. The overall environmental quality, measured using environmental quality index, has improved; however, the improvement only occurred in suburb districts. The variation of green land per capital, forestland and grassland were the main …
