Based on the 1961-2009 weather data from 21 meteorological stations in Ningxia, this paper analyzed the spatiotemporal variation trend of regional agricultural climate resources in Ningxia, Northwest China. In 1961-2009, the air temperature in Ningxia increased gradually from south to north, with the mean annual temperature increased by 0.4 degrees C x (10 a)(-1) , while the annual precipitation in most regions decreased gradually, with a decrement 4.26 mm x (10 a)(-1). Both the frost-free period and the duration of crop growth season prolonged. The regions with > or = 10 degrees C accumulated temperature being > or = 3200 degrees C x d extended southwardly, and thereby, the regions adaptive for planting mid and late rice increased. In 2001-2009, most regions were adaptive for plating winter wheat, and the whole Ningxia was adaptive for plating spring wheat. In the southern mountain regions, the region with mean temperature in July being < or = 20 degrees C decreased gradually, and accordingly, the regions adaptive for planting potato decreased.

Based on data of 24 weather stations in Ningxia from 1981 to 2010, combined with the wine grape sampling test results and other zoning indexes, starting from the concept of high-quality ecological zones of viticulture, the frost-free period, > 10 C accumulated temperature, precipitation in harvest period, soil type and slope position were used in high-quality ecological regionalization of wine grape varieties in Ningxia by using optimization method and GIS technique. The distribution maps of high-quality ecological viticulture of main red varieties and white varieties were suggested for wine grape growers. All red varieties including extremely late ripening variety ‘Grenache’, mid to late ripening variety ‘Cabernet Sauvignon’, mid ripening variety ‘Merlot’, and early ripening variety of ‘Pinot Noir’ are suitable for planting in Ningxia, and those varieties had great potential for exploitation. It should be focused on the development in high-quality ecological zone of wine grape in the Western Xia imperial tombs region in Yinchuan, Gezi Mountain in Qingtongxia, and the Baima and Shikong mountain areas in Zhongning. Regional planting areas for early and mid ripening varieties, such as ‘Pinot Noir’, ‘Chardonnay’, ‘Riesling’, should be located in the central arid zone and Qingshui River basin. © 2014, editorial Board of Chinese Journal of Ecology.

The study of soil moisture distribution of dry land crops can supply scientific evidences for water resource use. The article studied dynamic changes of soil water of five kinds dry land- winter wheat, flax, potato, alfalfa and natural grass in different stages. The results showed that temporal variations of soil moisture on different dry land crops were similar. All five kind crops include "soil moisture content raising period" and "soil moisture content declining period", that dividing line were at the middle of July. Soil moisture of annual crops (as winter wheat, flax and potato) were more higher perennial crop (as alfalfa and natural grass) in whole growing time. The soil moisture vertical distribution of winter wheat, flax and potato were 'topsoil highness, subsoil lowness', alfalfa and natural grass in reverse. Topsoil moisture movement was obvious, subsoil moisture movementwas inconspicuous all dry crops. In growing time, rainfall didn't satisfy the all crops needs. The raising soil moisture in autumn is pivotal for harvest of dry crops.

Frost is a major agricultural meteorological disaster in Ningxia. Frost risk assessment and zoning can provide a valid basis for the regional disaster prevention and mitigation. Based on the information of meteorological observation data from 1981 to 2010 in Ningxia 23 weather stations, socioeconomic and geographic information data, and by the methods of risk index, analytic hierarchy process, weighted composite score, late frost disaster risk was evaluated, and the frost disaster risk zoning maps were completed with GIS. The results show that, the environmental sensitivity of the late frost is complex. The sensitivity in the northern irrigation areas is lower than in the mountain areas; hazard risk is generally on the high side; vulnerability of the hazard-affected body is the highest in the most of northern irrigated areas, next to the highest is in the south areas, and the central part is the lowest; the capacity of disaster prevention and mitigation is the highest in the irrigation areas, and lower in central and southern mountain areas; the highest risk areas of late frost disaster are concentrated in Yongning, Wuzhong of the northern irrigated area and Pengyang in the south, the small risk areas were concentrated in the north of the irrigated area and most of the central area.

The development of wine industry is greatly influenced by the market in China, being not perfect. Planning and regionalization for production areas are one of the main ways to promote ecological development of wine industry. Comprehensively using the methods of fuzzy mathematics, optimization and stepwise division, the ecological regionalization for dry red wine grape varieties in northern China where dry red wine dominates the wine industry was completed with small grid simulation methods, spatial analysis and layer operation supported by GIS. The results showed that the most ecologically suitable areas of dry wine grape varieties distributed in the following areas: the south section of Daxinanling Mountains region, counties in Western Liaoning Corridor region; most areas of Shangdong Peninsula surround the Bohai Gulf, Qinhuangdao districts and most of Liaodong Peninsula; most of Zhangjiakou and Datong in the border areas of Hebei and Shanxi provinces; the areas on the two sides of Helan Mountain and along the Yellow River in the northwestern region of China; areas in the Yili Valley and along the eastern Tianshan Mountain in Xinjiang. © 2014, editorial Board of Chinese Journal of Ecology.
