| 巢湖流域内各生态要素紧密联系，城市开发使其土地利用功能发生巨大变化，导致区域生态退化、生态屏障功能减弱，明晰土地利用变化特征及生态效应,有利于促进流域高质量发展。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；1980-1990年转换较少，主要是少量生态、生产空间互转；1990-2000年农村生活空间侵占大量耕地，2000年之后城镇快速发展，侵占农村、生态空间。（2）空间上，城镇、工矿、耕地空间重心转移明显，2000年之后土地转移主要集聚在城市发展区。（3）生态效应上，1990年之后生态环境质量持续下降，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。 |

| The ecological elements in the Chaohu Lake basin are closely linked, and urban development has caused great changes in land use functions, resulting in regional ecological degradation and weakening of ecological barrier functions, so it is helpful to clarify the characteristics of land use changes and ecological effects to promote high-quality development in the basin. Taking Chaohu Lake basin as an example, we construct a land use dominant function classification system based on "three living spaces", analyze the evolution characteristics of land use functions based on five periods of land data in 1980, 1990, 2000, 2010 and 2020, use transfer matrix and mapping, shift of center of gravity, and use ecological effect The results show that: (1) quantitatively, the land use function of the land was not affected by the land use function. The results show that: (1) quantitatively, the area of living space increases significantly, the area of production space decreases greatly, and the area of ecological space is relatively stable; the conversion from 1980 to 1990 is relatively small, mainly a small amount of ecological and production space is transferred to each other; from 1990 to 2000, rural living space encroaches on a large amount of arable land, and after 2000, towns develop rapidly and encroach on rural and ecological space. (2) Spatially, the spatial center of gravity of towns, industry and mining, and arable land shifted significantly, and the land transfer after 2000 was mainly concentrated in urban development areas. (3) In terms of ecological effect, the quality of ecological environment continues to decline after 1990, and the dense urban and rural living space is the main low-value agglomeration area. (4) In terms of ecological contribution, the main transformation leading to the deterioration of ecological environment is the encroachment of urban and rural construction space on arable land, forest land and grassland, while the main transformation making it improve is the conversion of arable land to forest land and water. |
