Spatio-temporal variation in China’s climatic seasons from 1951 to 2017
MA Bin, ZHANG Bo, and JIA Lige
In this paper, meteorological industry standard, daily mean temperature, and an improved multiple regression model are used to calculate China’s climatic seasons, not only to help understand their spatio-temporal distribution, but also to provide a reference for China’s climatic regionalization and crop production. It

Differential changes in precipitation and runoff discharge during 1958-2017 in the headwater region of Yellow River of China
HOU Bingfei, JIANG Chao, and SUN Osbert Jianxin
Maintenance of steady streamflow is a critical attribute of the continental river systems for safeguarding downstream ecosystems and agricultural production. Global climate change imposes a potential risk to water supply from the headwater by changing the magnitude and frequency of precipitation and evapotranspiration

Exploring the spatio-temporal impacts of farmland reforestation on ecological connectivity using circuit theory: A case study in the agro-pastoral ecotone of North China
LIU Xiaojing, LIU Dianfeng, ZHAO Hongzhuo, HE Jianhua, and LIU Yaolin
Farmland reforestation can contribute substantially to ecological restoration. Previous studies have extensively examined the ecological effects of farmland reforestation, but few of them have investigated the spatiotemporal responses of broad-scale landscape connectivity to reforestation. By using a typical agro-pasto

A study of the construction times of the ancient cities in Ganjia Basin, Gansu Province, China
XIA Huan, ZHANG Dongju, WANG Qiang, WU Duo, DUAN Yanwu, and CHEN Fahu
The Ganjia Basin in Xiahe County, Gansu Province, China, is located on the northeastern edge of the Tibetan Plateau. The area lies in the transitional zone between the Plateau ethnic groups dominated by ancestral Tibetans, and the Central Plains dynasties dominated by ancestral Han in history. The Ganjia Basin is there

Magnetic characteristics of lake sediments in Qiangyong Co Lake, southern Tibetan Plateau and their application to the evaluation of mercury deposition
GAO Xing, KANG Shichang, LIU Qingsong, CHEN Pengfei, and DUAN Zongqi
Heavy metals, one of the most toxic classes of pollutants, are resistant to degradation and harmful to the biological environment. The lakes that have developed on the Tibetan Plateau are ideal regions to investigate historic heavy metal pollution, particularly through the use of the reliable210Pb dating technique. Env

GIS and DEM based analysis of incision and drainage reorganization of the Buyuan River basin in the upper Lancang-Mekong of China since the Late Pleistocene
GU Zhenkui, FAN Hui, and YANG Kun
River incision and drainage reorganization have an important impact on the site selection of many major projects including city, road and others, and are the key issues of Quaternary environmental changes. Studies of river incision and river-network adjustment have traditionally been based on extensive field evidence,

Ecosystem carbon storage under different scenarios of land use change in Qihe catchment, China
ZHU Wenbo, ZHANG Jingjing, CUI Yaoping, and ZHU Lianqi
Regional land use change is the main cause of the ecosystem carbon storage changes by affecting emission and sink process. However, there has been little research on the influence of land use changes for ecosystem carbon storage at both temporal and spatial scales. For this study, the Qihe catchment in the southern par

Spatial patterns of Pinus tabulaeformis and Pinus massoniana forests in Qinling-Daba Mountains and the boundary of subtropical and warm temperate zones
YAO Yonghui, HU Yufan, KOU Zhixiang, and ZHANG Baiping
The Qinling Mountains is not only the geographical boundary between North and South China, but also the boundary between subtropical and warm temperate zones. It plays an important role in the geo-ecological pattern of China. However, there is controversy about the specific location of this geographical boundary in aca

Iterative construction of low-altitude UAV air route network in urban areas: Case planning and assessment
XU Chenchen, LIAO Xiaohan, YE Huping, and YUE Huanyin
With the rapid increase of Unmanned Aircraft Vehicle (UAV) numbers, the contradiction between extensive flight demands and limited low-altitude airspace resources has become increasingly prominent. To ensure the safety and efficiency of low-altitude UAV operations, the low-altitude UAV public air route creatively propo
