可持续发展目标(SDGs)呼吁全世界共同采取行动,促进繁荣并保护地球.本研究面向SDGs构建了环境、粮食和经济等可持续发展情景,预测2020~2030年丝绸之路沿线国家的土地利用变化,并分析其对陆地碳库的影响。研究表明:未来土地利用变化及其对陆地碳库的影响在不同情景下存在显著差异。在可持续环境情景下,林地得到了有效保护,相较于2020年中国林地碳储量增加了约0.60%;在可持续粮食情景下,耕地流失得到了缓解,尤其在南亚及东南亚地区的耕地面积呈现上升趋势:在可持续经济情景下,城市扩张速度加快,引起的碳损失量最多这项研究有助于推进丝绸之路沿线甚至全球可持续发展进程,为探寻可持续发展路径提供了科学依据。

BACKGROUND： Sclerosing cholangitis（SC） is a chronic cholestatic hepatobiliary disease with uncertain long-term prognosis in pediatric patients. This study aimed to evaluate longterm results in children with SC according to the types of ***： We retrospectively followed up 25 children with SC over a period of 4-17 years（median 12）. The diagnosis of SC was based on biochemical, histological and cholangiographic findings. Patients fulfilling diagnostic criteria for probable or definite autoimmune hepatitis at the time of diagnosis were defined as having autoimmune sclerosing cholangitis（ASC）; other patients were included in a group of primary sclerosing cholangitis（PSC）. The incidence of the following complications was studied： obstructive cholangitis, portal hypertension, advanced liver disease and death associated with the primary ***： Fourteen（56%） patients had PSC and 11（44%） had ASC. Patients with ASC were significantly younger at the time of diagnosis（12.3 vs 15.4 years, P=0.032） and had higher Ig G levels（22.7 vs 17.2 g/L, P=0.003）. The mentioned complications occurred in 4（16%） patients with SC, exclusively in the PSC group： one patient died from colorectal cancer, one patient underwent liver transplantation and two patients, in whom severe bile duct stenosis was present at diagnosis, were endoscopically treated for acute cholangitis. Furthermore, twoother children with ASC and 2 children with PSC had elevated aminotransferase levels. The 10-year overall survival was 95.8% in all patients, 100% in patients without complicated liver disease, and 75.0% in patients with ***： In children, ASC is a frequent type of SC, whose prognosis may be better than that in patients with PSC.

The purpose of this paper is to contribute to the definition of a European perspective on Digital Earth(DE),identify some actions that can contribute to raise the awareness of DE in the European context and thus strengthen the European contribution to the International Society for Digital Earth(ISDE).The paper identifies opportunities and synergies with the current policy priorities in Europe(Europe 2020,Innovation Union and Digital Agenda)and highlights a number of key areas to advance the development of DE from a European perspective:(1)integrating scientific research into DE;(2)exploiting the Observation Web with human-centred sensing;and(3)governance,including the establishment of stronger linkages across the European landscape of funding streams and *** paper is offered also as a contribution to the development of this new vision of DE to be presented at the next International DE Conference in Perth,Australia,in August *** global recognition of this new vision will then reinforce the European component and build a positive feedback loop for the further implementation of DE across the globe.
