| 1 | 青藏高原生态屏障区生态系统服务权衡与协同关系显示文摘为了开展多种生态系统服务的可持续管理决策,厘清生态系统服务权衡与协同关系是重要的前提。以青藏高原生态屏障区为对象,采用土地利用数据、土壤数据、气象数据和DEM数据,分析了2000—2015年土壤保持、水源涵养和碳储量服务的时空变化,识别了3种生态系统服务供给热点区,并分析了不同生态系统服务权衡与协同关系。结果表明:(1)青藏高原生态屏障区3种生态系统服务土壤保持、水源涵养和碳储量服务在空间上均表现为由东南向西北减少的趋势;(2)2000—2015年水源涵养和土壤保持服务呈现下降趋势,减少量分别为95.27 mm和1081.38 t/hm 2,碳储量呈现增加趋势,增加量为25.77 g C/m 2;(3)研究区1类和2类热点区面积减少,3类热点区以及非热点区面积增加,林地提供3种服务的能力强于草地;(4)在空间上,2000—2015年这3种生态系统服务两两之间的协同关系在变强,具体表现为相关系数的增加。在时间上,3种生态系统服务两两之间的协同关系在变弱,具体表现为相关系数的减少。研究区3种生态系统服务在时空上存在不同的变化趋势;各服务间存在显著的协同关系,且随着时空变化协同关系也存在强弱变化。 | 朱殿珍 初磊 马帅 王良杰 张金池 | 2021 | 水土保持研究2021，28，4： | 14 |
| 2 | Advances in Ecological Applications of Fengyun Satellite Data显示文摘In recent years,the remote sensing based on meteorological satellite observations has become an important tool for assessing global ecological conditions.Since the early 2000,Fengyun(FY)satellite data have been widely used to derive the key parameters of ecological environment in China.An integrated earth-observation system has been developed in China through using FY satellite data,including retrievals the key ecological parameters as well as to constructions of long-term data records of vegetation index,land surface temperature,net primary production,vegetation health index,and so on.Considerable progress has thus been made in the application and service for prevention of air pollution,management and control of ecological redline,ecological monitoring for the Belt and Road Initiative,and assessment of ecological environment for human settlement.In order to monitor the ecological parameters in real time and with a full dynamic coverage,it is necessary to improve the technology in application of ecological remote sensing from meteorological satellites,and further enhance the ecological meteorological service. | Xiuzhen HAN Hao GAO Jun YANG Yachun LI Weicheng GENG | 2021 | Journal of Meteorological Research2021，35，5： | 1 |
