Abstract：
Land use transition and its impact on ecosystem service value (ESV) are the foundation for optimizing the layout of territorial space and ecological civilization construction. With the acceleration of industrialization and urbanization, the area of construction land expands in China. To accurately estimate the ESV in industrial counties, the impact of construction land on the ecological environment should be fully considered. This paper took Gangcheng District, Jinan City, a steel base in the Shandong Province of China as an example, then the value coefficients of \"three wastes\" factors (waste gas, wastewater, and waste) were introduced, and an improved calculation method of ESV was put forward for industrial counties in combination with remote sensing and land use data. Finally, the land use transition and its ESV effect in typical industrial counties were analyzed using geo-informatic Tupu and grid method. The results showed that the most important land use transitions were from grassland and forestland to cultivated land, from cultivated land and forestland to construction land in 1990-2010, and from cultivated land transformed to forestland in 2010-2021. The types of land use transition were mainly repetitive and continuous. The ESV first decreased and then increased, with a slight overall decline for more than 30 years, showing a spatial distribution characteristic of \"low in the south-central and high around.\" Land use transition had the impact on ESV with the negative contribution rate of 68.28% in 1990-2000 and 73.16% in 2000-2010, mainly caused by the transition from forestland and grassland to cultivated land and construction land, and the positive contribution rate of 81.72% in 2010-2021, mainly caused by the transition from cultivated land to forestland. Compared with the ESV calculation method without introducing the \"three wastes\" factor and Xie Gaodi\'s method, the improved method in this paper considered the inevitable impact of construction land on ESV in industrial counties and made the ESV calculated more accurate according to the regional nature. This paper cannot only enrich the theories and technical methods of land use transition and its effects, and provide a case reference for similar industrial counties, but also provide data and decision-making support for the spatial layout and ecological protection in the study area.
摘要：
土地利用转型及其对生态系统服务价值的影响是优化国土空间布局和生态文明建设的基础。随着工业化和城市化进程的加快,中国建设用地面积不断扩大。为了准确估计工业县的ESV，应充分考虑建设用地对生态环境的影响。本文以钢城区为例，济南市,以中国山东省的钢铁基地为例，然后是“三废”因素的价值系数(废气，废水,和废物)被引入，结合遥感和土地利用数据，提出了一种改进的工业县域ESV计算方法。最后,利用地理信息学图普和网格方法分析了典型工业县的土地利用转型及其ESV效应。结果表明,从草地、林地到耕地的土地利用过渡最为重要,1990-2010年从耕地和林地转变为建设用地，2010-2021年从耕地转变为林地。土地利用过渡类型以重复和连续为主。ESV先减小后增大,30多年来总体略有下降，表现出“中南部低，周围高”的空间分布特征。“土地利用转型对ESV产生了影响，1990-2000年的负贡献率为68.28%，2000-2010年的负贡献率为73.16%，主要是由林地和草地向耕地和建设用地的过渡引起的，和2010-2021年的正贡献率为81.72%，主要是由耕地向林地过渡所致。与未引入“三废”因子的ESV计算方法和谢高迪的方法相比,本文的改进方法考虑了工业县城建设用地对ESV不可避免的影响，使ESV根据区域性质计算更加准确。本文不仅丰富了土地利用转型及其效应的理论和技术方法,为类似工业县提供案例参考，同时也为研究区的空间布局和生态保护提供数据和决策支持。
