【摘要】：什么是好的土地利用格局?长期以来土地利用学无法很好地回答该问题,其原因是土地利用景观格局评价不仅缺乏普适性的评价体系和评价方法,还缺乏稳定的价值导向和针对性。本文考虑格局与功能的关系,选取易获取的评价指标,构建"生态系统活力—生态系统组织—生态系统弹性—生态系统服务"评价指标体系。通过处理栖霞市1987、2015年两期遥感数据,运用平均归一化植被指数,景观格局指数、生态系统弹性系数、生态系统服务系数、空间邻近效应系数等对栖霞市的土地利用景观空间绩效状态进行时空量化分析。结果表明,1987—2015年间栖霞市生态系统活力和生态系统服务处于较高水平,生态系统弹性和生态系统组织水平下降;土地利用景观空间绩效综合指数平均值分别为0.67和0.61,表明研究期间栖霞市土地利用景观空间绩效水平呈稳中稍降的趋势,主要原因是城乡建设用地扩张以及农用地的开发。
[Abstract]:What is a good land use pattern? For a long time, land use science can not answer this question well, the reason is that land use landscape pattern evaluation is not only lack of universal evaluation system and evaluation method. There is also a lack of stable value orientation and pertinence. Considering the relationship between pattern and function, this paper selects easily accessible evaluation indicators. The evaluation index system of "ecosystem vitality-ecosystem organization-ecosystem elasticity-ecosystem service" was constructed. Through processing the remote sensing data of Qixia city in 1987 and 2015, the average normalized vegetation index and landscape pattern index were used. Ecosystem elasticity coefficient, ecosystem service coefficient, The spatial proximity effect coefficient was used to quantitatively analyze the spatial performance of land use landscape in Qixia City. The results showed that the ecosystem vitality and ecosystem service of Qixia City were at a high level from 1987 to 2015. The average value of land use landscape spatial performance index was 0.67 and 0.61respectively, which indicated that the land use landscape spatial performance level of Qixia city showed a steady and moderate decline trend during the study period, and the average value of land use landscape spatial performance index was 0.67 and 0.61, respectively. The main reason is the expansion of urban and rural construction land and the development of agricultural land.
