In this study, the carbon emissions(CEs) from cultivated land(CL) were included as an undesirable output in the utilization efficiency of such land. A slack-based model was used to calculate the CL use efficiency(CLUE) for 11 provinces and cities in th

Urbanization and eco-environment coupling is a research hotspot. Dynamic simulation of urbanization and eco-environment coupling needs to be improved because the processes of coupling are complex and
Saltwater intrusion in the estuary area threatens the use of freshwater resources. If river discharge increases to a critical value, then saltwater intrusion frequency and salinity level decreases. In
Extreme weather is an important noise factor in affecting dynamic access to river morphology information. The response characteristics of river channel on climate disturbances draw us to develop a met
The concept of ‘Beautiful China is a new goal of ecological construction in the new era of socialism and aims to meet the needs of people as they strive for a better life. National land spatial planni
The Chinese government ratified the Paris Climate Agreement in 2016. Accordingly, China aims to reduce carbon dioxide emissions per unit of gross domestic product(carbon intensity) to 60%–65% of 2005
Climate change resulting from CO_2 emissions has become an important global environmental issue in recent years. Improving carbon emission performance is one way to reduce carbon emissions. Although c
Finding accurate methods for estimating and mapping land prices at the macro-scale based on publicly accessible and low-cost spatial data is an essential step in producing a meaningful reference for r
2010年起,重庆市政府安排市规划和自然资源局牵头,市公安交管局、市交通局等部门配合,建设"重庆市交通综合信息平台",作为全市交通数据汇集、共享、应用的基础平台。2015年后又对平台进行了拓展和深化,建设重庆市交通决策支持系统,作为全市面向交通规划、建设和管理的综合决策应用支撑平台。经过8年多的持续建设,在相关部门的支持下,"重
农耕文明时期,一切农活都要靠农民辛勤劳作才能完成。如今,借助千寻位置覆盖全国的精准时空网络,上天下地的机器人插上了"时空智能"的翅膀,在农业中扮演越来越重要的角色。在空中,基于精准时空数据,植保无人机开展自主飞行作业,春能播种、夏能喷药,效率提升。在地面,基于精准时空数据的农机也逐步实现自动化。
智慧交通是大数据、人工智能、5G应用等高新科技与交通运输深度融合的新兴业态,是提升综合交通质量效率的重要手段,也是抢占新一轮科技革命和产业变革先机的重要力量。十九大报告明确提出贯彻"交通强国"新发展理念,意味着我们将在新时代开启建设交通强国新征程。加快推进综合交
