	Abstract:In this paper, based on the remote sensing image of Landsat7 TM/ETM, the ArcGIS10.3 software is used to interpret the land use in Yantai 2015, and the Land Use Remote sensing classification of China\'s coastal zone is classified as the basis, then the land use status of Yaitai 2015 is obtained. The paper analyzes the matching relationship between land use status and economic development by combining the state of economic development, relevant literature and related Yearbook. The following conclusions are drawn: ①The main land utilization type of Yantai 2015 are arable land, woodland, garden and construction sites, while the unused land area is very small. ②The protection of coastal wetlands in Yantai has been better in recent ten years, and the methods of inshore aquaculture and other utilization have increased. ③ The development and policy of Yantai economy is the main driving force of the change of land use mode. ④ The Yantai city belongs to the retarded type of land use benefit, and the development degree of barely coordinating can′t provide a big impetus for economic development.

	Abstract:In order to study the land use change situation of Qingdao in recent 10 years, this paper used the land Use classification system of China\'s coastal zone to overlay the land use of 2015 by visual interpretation with 2005 data in Arcgis10.2. The results showed that the residence of Qingdao increased 1612.3km2, the area of urban mining increased 351.2km2, the area of woodland increased 499.7km2, and the area of arable land decreased 1911.9km2, the grassland areas decreased 342.4km2, and the water body decreased 277.4km2. These changes were mainly due to the speed of urbanization, another reason was that the Government attached importance to environmental issues, vigorously carried out afforestation and returned farmland to forest. The research provided scientific basis for local government departments to formulate targeted land use planning and policies, which is of great practical significance for regional comprehensive, coordinated and sustainable development.

	Abstract:Eddy kinetic energy (EKE) is one key dynamic parameter to characterize atmospheric circulations and synoptic-scale disturbance activities. Investigation of the distribution and variability of atmospheric EKE and related energy conversion components over the South China Sea (SCS) can help us to better understand the dynamics of the SCS monsoon and tropical cyclone (TC) formation in this region. We present our investigation on the interannual variations of low-level (850-hPa) atmospheric EKE over the SCS in this study. Both northern and southern SCS experienced prominent interannual variation in the 850-hPa EKE during their most active EKE months. The energy processes for generation and maintenance of the EKE were analyzed based on the EKE tendency equation. Results suggested that the barotropic energy conversion (BEC) term made the largest contribution to the interannual variation of the EKE over both northern and southern SCS. The interannual variation of the BEC over the southern SCS was mainly modulated by the El Ni?o-Southern Oscillation (ENSO) and had a close anti-correlated relationship with the sea surface temperature (SST) in the eastern equatorial Pacific. In contrast, the interannual variation of the BEC over the northern SCS was identified to be closely associated with the zonal SST gradient between the central equatorial Pacific and northern Indian Ocean. The atmospheric circulation anomalies in responses to SST anomalies enhanced the zonal wind shear over the SCS, giving rise to more BEC. The interannual variation of the BEC over the southern SCS was positively correlated with the TC formation number, with more (less) TCs formed during enhanced (suppressed) BEC years. However, the correlation between the BEC and TC formation number over the northern SCS was not significant, which may be due to the offsetting effects on TC formation by the cooling (warming) of the local SST during enhanced (suppressed) BEC years. These results could improve our understanding of the behaviors and causes of interannual variation in the low-level atmospheric EKE and its relationship with interannual variation of the TC formation number over the SCS. The results highlighted the differences in the regional climate variability between the northern SCS and the southern SCS. ?????

	Abstract:There have a large number of slope movements occurred in China annually. Especially, fatal landslides are the most hazardous, causing serious fatalities and significant economic loss. In this study, the data of fatal landslides were collected from China geological environment information site and Ministry of Land and Resources of China in the period 2004-2016. Then a statistical analysis of the data was carried out to explore the trend of fatal landslide and the distribution of its losses in economic and fatality. In the studied period, a total of 4,718 deaths are collected resulting from 537 fatal landslides. It represents a frequency of 42 events and an average of 363 deaths every year. Meanwhile, fatal landslides fatalities are getting closer to total deaths of all geological hazards with the disaster records improvement. Although the economic loss of fatal landslides accounts for a small proportion of all hazards loss, however, the total amount is still enormous, 6.75 billion yuan recorded. The spatial distribution of fatal landslides shows intensive clusters in Southwest and Southern China, particularly densely distributing in Sichuan, Yunnan, and Hunan. Then the temporal distribution reveals a strong correlation with the main raining season, with the largest quantity of events occurring between June and September. Among the fatal landslides of which triggering factors have been recognized, 81.8% are associated with rainfall. This research gives a comprehensive recognition of fatal landslides trend and provides baseline information for disaster prevention and mitigation.
