- 摘要:
- 以广东省21个地级市为研究单元,运用GIS空间分析技术并结合广东省1990—2015年六期遥感数据,探究广东省“三生空间”用地转型的时空演变格局与生态环境效应。结果表明:(1)1990—2015年期间,广东省“三生空间”用地结构发生明显变化,主要表现为生产用地减少,生态用地略有下降,生活用地大幅度增加;(2)省内不同经济区域“三生空间”用地转型特征不同,但普遍存在农业生产用地减少、城镇生活用地与工业生产用地大幅增加;(3)整体上看,1990—2015年广东省生态环境质量略有恶化,由0.645下降到0.639,年均下降0.191%; 生态环境高质量区主要分布在粤西北,珠三角地区大部分处于生态环境低质量区,生态环境亟待提升。基于“三生空间”功能视角研究土地利用转型及其生态环境效应,可为广东省“三生空间”用地合理功能分区、生态文明建设提供依据。
- Abstract:
- Taking 21 prefecture-level cities in Guangdong Province as the research units, were used GIS spatial analysis technology and the six-period remote sensing data of Guangdong Province from 1990 to 2015 to explore the spatial and temporal evolution pattern and ecological environment effects of the ‘ecological-production-living' spaces land use transformation in Guangdong Province. The results show that, from 1990 to 2015, the land use structure of ‘ecological-production-living' spaces in Guangdong Province had changed significantly due to the reduction of production land, a slight decrease in ecological land use, and a significant increase in living land. The characteristics of land use transformation are different, but there wrer a general decreases in agricultural production land, urban living land and industrial production land. Overall, from 1990 to 2015, the ecological environment quality of Guangdong Province deteriorated slightly from 0.645 to 0.639. The average annual decline was 0.191%. The high-quality ecological environment mainly distributed in the northwest of Guangdong, and ecological environment of most of the Pearl River Delta was the low-quality, and the ecological environment should be improved. Based on the perspective of ‘ecological-production-living' spaces, the study of land use transformation and its eco-environmental effects can provide a basis for the rational functional division and ecological civilization construction of the ‘ecological-production-living' spaces in Guangdong Province.
