Effects of Production-Ecological-Living Land Use Transformation on Eco-environment Quality in Guangdong Province During 1980-2018
,农业生产用地和林地生态用地间转换现象明显。②“三生”用地空间转型主要表现为工矿生产用地、林地生态用地中心逐渐靠近广东省几何中心,农业生产用地、城镇生活用地中心逐渐远离几何中心。③广东省生态环境质量指数从1980年0.648 1降至2018年的0.641 4,生态环境质量空间分异明显,呈现“沿海低—内陆高”的分布特点。④Getis-Ord G
[Objective] The effects of production-ecological-living land use transformation on eco-environment quality in Guangdong Province were studied based upon grid cell in order to provide scientific basis for coordinated development of regional ecology and economic. [Methods] Based on the eight-phase Landsat TM image interpretation data of Guangdong Province and the dominant function classification system of land use in production-ecology-living space
and the characteristics of production-ecological-living land use transformation as well as its eco-environment quality were quantitatively analyzed. [Results] ① From 1980 to 2018
the agricultural productive land decreased greatly
with a total decrease of 5 369.61 km2 and the mining productive land and urban living land increased greatly
with a total increase of 4 526.02 km2 and 2 406.93 km2. The conversion between agricultural production land and woodland ecological land was obvious. ② Spatial transformation of production-ecological-living land use in Guangdong Province was mainly manifested as the mean center of mining productive land and forest ecological land became closer to the geometric center of Guangdong Province
the mean center of agricultural productive land and urban living land moved away from geometric center. ③ The index of eco-environment quality in Guangdong Province was reduced from 0.648 1 in 1980 to 0.641 4 in 2018. The spatial differentiation of ecological environment quality was obvious
and the eco-environment quality in coastal cities was much lower than inland area. ④ The Getis-Ord Gi* index proved that the hot region of the change of eco-environment quality was concentrated on the Eastern
Western and Northern regions of Guangdong Province
while the cold region was chiefly located in Pearl River Delta. ⑤ Guangdong Province had two trends which were ecological improvement and ecological deterioration. [Conclusion] Full consideration should be given to the regional natural considerations
the function positioning and the leading factors of ecological environment changes in order to formulate land policies and measures and promote the balanced development of Guangdong Province.
