摘要
[目的]探究国土空间变化对生境质量的响应机制,为国土空间规划和生态环境保护提供依据。[方法]以湖北省为研究对象,基于2000-2020年的土地利用数据,运用InVEST模型评估生境质量的时空演变特征,从三生空间的视角研究了区域生境质量对国土空间类型转变的响应程度。[结果](1)湖北省20年间国土空间利用强度逐年升高,国土空间类型转换中生产空间向生态空间转化面积最多,占比3.86%。(2)生境质量退化指数逐渐增长,生境退化度逐期升高;平均生境质量在时间分布上呈先升高后降低再升高的波动变化趋势,在空间分布上总体表现为“西北高,东南低”的空间格局。(3)生境质量下降的国土空间类型主要发生在生态空间向生产空间和生活空间的转变,以及生产空间向生活空间的转变,即生态空间的增加有助于改善区域生境质量,而生活空间的增多则会降低区域生境质量。[结论]2000-2020年湖北省生境质量受国土空间变化影响较大,关注国土空间类型转变,严格控制建设用地规模,可为合理制定国土空间规划和生态保护实践提供理论参考。
[Objective]The aims of this study are to explore the response mechanism of territorial spatial change to habitat quality,and to provide reference for territorial spatial planning and ecological environmental protection.[Methods]Based on the land use data from 2000 to 2020 in Hubei Province,the InVEST model was used to evaluate the temporal and spatial evolution characteristics of habitat quality,and the response degree of regional habitat quality to the change of territorial spatial type was explored from the perspective of tertiary space.[Results](1)In Hubei Province,the intensity of land use increased year by year in the past 20 years.In the conversion of land space type,the conversion area of production space to ecological space was the largest,accounting for 3.86%.(2)The habitat quality degradation index increased gradually,and the habitat degradation degree increased gradually.The average habitat quality increased first,then decreased and then increased in the temporal distribution,and the spatial distribution showed a spatial pattern of high level in the northwest and low level in the southeast.(3)The spatial types of habitat quality decline mainly occurred in the transformation from ecological space to production space and living space,and the transformation from production space to living space also led to a downward trend in habitat quality.Generally speaking,the increase of ecological space helped to improve regional habitat quality,while the increase of living space reduced regional habitat quality.[Conclusion]Habitat quality in Hubei Province from 2000 to 2020 was greatly affected by the change of territorial space.Paying attention to the change of territorial space type and strictly controlling the scale of construction land can provide theoretical reference for the rational formulation of territorial space planning and ecological protection practice.
