“鸟中国宝”东方白鹳

2023年12月28日,凉山州冕宁县林业和草原局工作人员在宁源湖开展全国越冬候鸟同步监测工作时,发现两只东方白鹳。东方白鹳是国家一级重点保护野生动物,属于大型珍稀候鸟,全世界野生东方白鹳仅有3000只左右,目前已经处于全球濒危状态,素有“鸟界国宝”“鸟类大熊猫”之称。它们对生存环境的要求极为苛刻,越冬地也主要集中在长江中下游的湿地湖泊,这是首次在宁源湖区域发现东方白鹳的踪迹。

Combining CLUE-S and SWAT Models to Forecast Land Use Change and Non-point Source Pollution Impact at a Watershed Scale in Liaoning Province, China

Non-point source(NPS) pollution has become a major source of water pollution. A combination of models would provide the necessary direction and approaches designed to control NPS pollution through land use planning. In this study, NPS pollution load was simulated in urban planning, historic trends and ecological protection land use scenarios based on the Conversion of Land Use and its Effect at Small regional extent(CLUE-S) and Soil and Water Assessment Tool(SWAT) models applied to Hunhe-Taizi River Watershed, Liaoning Province, China. Total nitrogen(TN) and total phosphorus(TP) were chosen as NPS pollution indices. The results of models validation showed that CLUE-S and SWAT models were suitable in the study area. NPS pollution mainly came from dry farmland, paddy, rural and urban areas. The spatial distribution of TN and TP exhibited the same trend in 57 sub-catchments. The TN and TP had the highest NPS pollution load in the western and central plains, which concentrated the urban area and farm land. The NPS pollution load would increase in the urban planning and historic trends scenarios, and would be even higher in the urban planning scenario. However, the NPS pollution load decreased in the ecological protection scenario. The differences observed in the three scenarios indicated that land use had a degree of impact on NPS pollution, which showed that scientific and ecologically sound construction could effectively reduce the NPS pollution load in a watershed. This study provides a scientific method for conducting NPS pollution research at the watershed scale, a scientific basis for non-point source pollution control, and a reference for related policy making.

Tectonic Mechanism of the Suining(Ms5.0) Earthquake,Center of Sichuan Basin,China

On Jan.31 of 2010,the Suining earthquake occurred at Suining City whch is located the center of Sichuan Basin.It is unusual for the strong earthquake to occur at the center of Sichuan Basin with a stable geotectonic environment and a low-level historical seismicity.The macro-epicenter of the earthquake is located at Moxi town of Suining city,Sichuan province,China.The earthquake intensity of the epicenter area is degree VII,and the long axis of the isoseismal line trends in NE orientation.The Suining earthquake caused the collapse or destruction of 460 family houses.The earthquake focal mechanism solution and records of the near-field seismographic stations showed the earthquake occurred at the reverse fault at a depth 34 km.Based on the waveform and focal mechanism,we consider the Suning earthquake is triggered by the reverse fault and not by the gravitational collapse or man-made explosive sources.Basing on seismic refraction profile and borehole,we consider that the earthquake is triggered by the backthrust fault of Moxi anticline rooted in detachments at a depth 3-4 km.Furthermore,we infer that tectonic mechanism of the Suining(Ms5.0) Earthquake is driven by the horizontal crustal shortening and stress adjustment on a shallow detachment after the Wenchuan(Ms 8.0) earthquake.

Exploitation, Utilization Status, and Development Prospects of Water Resources in Ningbo City

Water resources insufficiency is one of the bottlenecks that restrict sustainable socio-economic development in Ningbo city. Good handling of the relationship between water resources utilization and development is of great significance for the realization of continuous economic growth and sustainable socio-economic development. This study systematically evaluated water resources utilization with respect to water supply and demand. Water resources development and utilization prospects and regional differences were then assessed at multiple scales, at both county/district and city level in Ningbo city, using the water resources carrying index. Results showed that：（1） The volume of water resources supply and consumption gradually rose each year, with surface water as the primary source and groundwater as the secondary source. Regarding consumption, industrial water consumption was the primary element, and domestic and environmental water consumption were the secondary elements. Even though the use of water resources for irrigation, secondary and, tertiary industry were becoming more efficient, comprehensive per capita water consumption was gradually increasing.（2） The water resources carrying index for Ningbo city fluctuated in the range of 4.51–23.35 during 2001–2015; the degree of water resource utilization and potential exploitation evaluation of water resources were not stable. The average value of the water resources carrying index was 11.68; the degree of utilization of water resources was very high, and the introduction of water from external water bodies was necessary, to the extent external source were available.（3） Future water resources exploitation will be quite difficult in Ningbo city, especially in Cixi county, Ningbo municipal district and Yuyao county. So the introduction of external water as a supplemental source will be required.
