Agent-based model of land system: Theory, application and modelling framework
DAI Erfu, MA Liang, YANG Weishi, WANG Yahui, YIN Le, and TONG Miao
Land change science has become an interdisciplinary research direction for understanding human-natural coupling systems. As a process-oriented modelling approach, agent based model (ABM) plays an important role in revealing the driving forces of land change and understanding the process of land change. This paper start

Impact of cultivated land fragmentation on spatial heterogeneity of agricultural agglomeration in China
XU Weiyi, JIN Xiaobin, LIU Jing, and ZHOU Yinkang
Systematically revealing the impact of cultivated land fragmentation (CLF) on the geographical agglomeration pattern of agricultural specialization (AS) has positive significance for national agricultural production management. Based on the data of the second national land survey and agricultural production, this study

Patterns and trends in grain self-sufficiency on the Tibetan Plateau during 1985-2016
SHI Wenjiao, LU Changhe, SHI Xiaoli, and CUI Jiaying
Capacity for grain self-sufficiency on the Tibetan Plateau (TP) is an important basis for ensuring social stability and regional sustainability. Thus, based on county-level statistical data for population, grain production and consumption, we analyzed patterns and trends in grain supply and demand at regional, provinci

Exploring the urban-rural development differences and influencing factors in the Huang-Huai-Hai Plain of China
CHENG Mingyang, LI Linna, and ZHOU Yang
Uneven urban and rural development is one of the main reasons for the decline of the countryside. This imbalance could be measured by the urban-rural difference index (URDI). Existing studies on urban-rural differences have focused on single dimension between urban and rural areas, and lack a systematic multi-dimension

Priority sites and conservation gaps of wintering waterbirds in the Yangtze River floodplain
XIA Shaoxia, YU Xiubo, LEI Jinyu, HEARN Richard, SMITH Bena, LEI Gang, and XIE Ping
The Yangtze River floodplain is critical for migratory waterbirds along the East Asian-Australasian Flyway (EAAF). Greater awareness of its global importance is urgently needed to ensure waterbird populations remain in favourable conservation status, as well as the enhancement of wider wetland biodiversity within this

Evolution characteristics and drivers of the water level at an identical discharge in the Jingjiang reaches of the Yangtze River
CHAI Yuanfang, YANG Yunping, DENG Jinyun, SUN Zhaohua, LI Yitian, and ZHU Lingling
The operation of large-scale reservoirs have modified water and sediment transport processes, resulting in adjustments to the river topography and water levels. The polynomial fitting method was applied to analyze the variation characteristics of water levels under different water discharge values in the Jingjiang reac

Using LiDAR-DEM based rapid flood inundation modelling framework to map floodplain inundation extent and depth
ZHANG Yongqiang
Mapping floods is important for policy makers to make timely decisions in regards to emergency responses and future planning. It is therefore crucial to develop a rapid inundation modelling framework to map flood inundation. This study develops an airborne scanning laser altimetry (LiDAR) digital elevation model (DEM)

Temperature variations evidenced by records on the latest spring snowing dates in Hangzhou of eastern China during 1131-1270AD
LIU Haolong, DAI Junhu, YAN Junhui, HE Fanneng, GE Quansheng, and MU Chongxing
We collected and verified documentary records of the latest spring snowing dates (LSSD) in Hangzhou during Southern Song Dynasty. Furtherly, the statistical correlation between this proxy and February-April mean temperature in Hangzhou was examined, and samples later than the perennial mean of the LSSD during Southern
