"Total expenditure（public and private） per capita spent on the preservation, protection and conservation of world heritage" is considered as an indicator to evaluate the sustainable development goals（SDGs） of world heritage by SDG11.4.1. It is in the state of having methods but no data, which needs the support of data and calculation cases. The statistical data of 48 UNESCO sites of China were used to measure and analyze SDG11.4.1, and Landsat images were used to monitor and analyze the human intervention of 4 natural heritage sites in this study. The results are shown as follows. 1) Expenditure per unit area can be used to measure the sustainable development status of natural protected areas（includes world natural heritage, mixed heritage, geopark and biosphere reserve）, which is not suitable for the measurement of cultural heritage. 2) The average investment of 4 million yuan per square kilometer per year in natural protected area can be used as the threshold for high-quality development goals, and the average expenditure per square kilometer of 800 000 yuan per year can be used as the threshold for good development status. 3) The degree of human intervention as an extended index can reflect the sustainable protection status and trend of heritages, and can be further applied in similar protected sites in China and other countries.

文章以"中国科技期刊卓越行动计划梯队期刊项目"《植物生态学报(英文版)》(Journal of Plant Ecology)为案例,分析了期刊的基本情况,并从提高刊物的视觉效果、提高论文的可见性、提高期刊的学术传播能力三方面阐述了该刊采取的一系列改革与创新举措,以期进一步提升期刊的质量和影响力,并为其他科技期刊提供有益的借鉴.

三北地区长期以来是生态建设和生态文明关注的重点区域,开展三北地区植被变化监测,可为后续三北生态建设提供科学依据. 基于长时间序列NDVI数据,采用趋势分析、变异系数和Hurst指数分析等方法对三北地区1998—2018年植被NDVI变化特征及其趋势的持续性进行模拟和分析. 研究结果表明:①1998—2018年间三北地区植被有所改善,NDVI上升区域与下降区域分界线大致以200 mm等降水量线为界,山西和陕西改善面积占比超过95%,新疆改善面积占比低于50%. ②近20 a三北地区80%以上的地区NDVI波动明显,波动区域与稳定区域大致以400 mm等降水线为界,新疆地区波动最为剧烈. ③三北地区Hurst指数均值为0.47,90%以上的区域NDVI变化趋势难以长久维持. 总体看,1998—2018年三北地区植被整体呈改善趋势,但可持续性不强,未来需要进一步加强植被生态修复与防护工作,保障生态文明建设的持续性.
