中文摘要: |
以巢湖流域为例,构建基于“三生空间”的土地利用主导功能分类体系,基于 1980年、1990年、2000 年、2010 年、2020 年五期土地数据,运用转移矩阵与图谱、重心转移,分析土地利用功能演变特征,运用生态环境效应模型分析生态效应规律。结果表明:①数量上,生活空间面积显著增加,生产空间面积大量减少,生态空间面积相对稳定。②空间上,城镇、工矿、耕地空间重心转移明显,2000 年后土地转移主要集聚在城区。③生态效应上,1990 年后生态质量持续下降,密集的城乡生活空间是主要低值集聚区。④生态贡献率上,导致生态环境恶化的主要转型为城乡建设空间对耕地、林地、草地的侵占,使其改善的主要转型则为耕地向林地、水域的转换。 |

Chaohu Lake basin as an example,a land use dominant function classification system is conducted based on “productionliving-ecological space”. The evolution characteristics of land use functions are analyzed by using transfer matrix and mapping method,center shift method,and the ecological effect law by ecological effect model based on five periods of land data in 1980,1990,2000,2010 and 2020. The results show that quantitatively,the area of living space increases significantly,while the production spacedecreases greatly,and the ecological space relatively stable. Spatially,the centers of towns,industrial and mining space,and arablelands shifted significantly,and the land transfer was mainly occured in urban development areas after 2000. In terms of ecologicaleffect,the ecological quality continues to decline after 1990,and the main low-value agglomeration area were dense urban and ruralliving spaces. In terms of ecological contribution,the main transformation leading to the ecological deterioration is the encroachment ofurban and rural construction space on arable lands,forest lands and grassland,while the main positive transformation is the conversionof arable lands to forest and water lands. |
