Based on spatial climatic data of agriculture and the experiment data, the models of agro-ecological assessment of climate for agricultural suitability in this study were developed using the fuzzy mathematical method. Three coefficients, in- cluding the resource coefficient (Cr), the efficiency coefficient (Ce), and the utility co- efficient (K), were used in the models, which were calculated based on temperature, moisture, and sunshine duration data of Guanzhong region, Shaanxi Province. The results indicated that resource coefficient was higher in west of the region than that in east, and higher in south (especially in the Central Shaanxi Plain) than that in the Weibei plateau. The value of Cr changed from 6.5 to 9.2 from north to plain area. Spatial change of efficiency coefficient was obvious, lower in the northeast than in the central plain, and the value of Ce changed from 2.3 to 6.5 from the northeast to the central plain. As for utility coefficient, it was lower in northeastern part of the Weibei plateau and in southern mountain areas than that in the central plain, showing significant latitudinal zonality. Furthermore, the value of K increased from 0.35 to 0.78 from northeast to the central plain, and decreased from 0.78 to 0.53 from the central plain to southern mountain areas. These indicated that climate resource in the central plain region was more abundant and potential, compared with other regions. GuanZhong region was classified into three larger agricultural zones and three small independent zones, according to agro-ecological assessment. Light, heat and water resources should be made use of in an efficient way in spatial allo- cation of agricultural production. For example, water facilities should also be im- proved in Weibei plateau region where highly-qualified fruit should be enhanced and fruit processing industrial chain should be shaped. Large-scale production area of wheat should be increased in central irrigation region and more vegetable bases should be developed around large and medium-scale cities. Thanks for outstanding water conservation function, the three-dimensional agriculture including medicine and other sideline production should be developed in Qinling Mountains and the special- ized commercial agriculture should be accelerated in independent small zones, ac- cording to local conditions. In the research, different crop varieties were developed in corresponding regions as per current eco-climatic conditions. 展开更多

Northern Shaanxi is located on the Erdos syncline, a subdivision of North China Shield. The loess landforms are the main landform types, additionally, there are low rocky mountains and hills, valleys and eolian landforms. Changes of techonic bases and of water-heat conditions in the region cause obvious regional differentiations of the landcape. From south to north,accompanying with uprising of the relief and decrease of mean annual temperature and precipitation, the types of landforms, degree of dissection,vegetation cover-degree and intensity of soil and water loesses show clearly latitudinal zonation. 展开更多

Based on conventional high-altitude aerial and ground data, regional intensive rainfall data, Doppler weather radar and satellite cloud data, the occurrence and development process of a regional rainstorm in South Shaanxi during July 17 -18, 2010 was discussed deeply. The results showed that the occurrence and development of the mesoscale weather system resulted in the heavy storm directly besides favorable large-scale background, and the the occurrence and development of the system had strong local and sudden characters. In addition, heavily concentrated wa- ter vapor in the troposphere at low and middle altitudes as well as existence of unstable conditions of convection might be favorable to the develop- ment of the system, while dynamic action of terrain, ground weak cold front and disturbance of the low-level jet stream might trigger the occurrence and development of the system. 展开更多

The theory of the country-of-origin image is discussed and the natural relations between county-of-origin image and the regional brand are explored.The paper points out that the dispersion of agriculture has intensified the natural relations to a large extent.The paper probes into the branding status of agriculture in Guanzhong-Tianshui economic zone and points out the problems of it.In the first place,the agricultural industrial system is complete but there is no unified agricultural regional brand;in the second place,the weak awareness on protecting brand leads to the irrational behaviors on damaging brand.From the perspective of the image of the country of origin,the branding mode of agriculture is established and the countermeasures on improving the competitiveness of agricultural products are put forward.Firstly,the leading role of the government should be fully displayed;secondly,the image protection of original production place and regional brand promotion of the agricultural region should be intensified;thirdly,the functions of local pillar industries in protecting image and regional branding should be fully made use of. 展开更多

The implementation of the rural resettlement policy in southern Shaanxi has produced a lot of rural immigrants that need urgent resettlement. The subsequent settlement problem is the core issue of migration policy. All kinds of special background and demand of these "rural immigrants" put forward new requirements for resettlement planning. This paper explored the planning of rural immigrant relocation under the guidance of tourism industry, so as to create a new living environment for immigrants inheriting traditional cultural context, and revitalize the new urbanization of south Shaanxi. First, the paper briefly introduced the background of the rural resettlement policy in south Shaanxi. Second, taking the Phoenix Mountain Resort Park in Hanyin County for example, this paper used SWOT to analyze the feasibility of immigrant relocation in comprehensive tourist service area. Third, this paper elaborated the specific concepts and schemes. 展开更多

More than 240 items of historical records containing climatic information were retrieved from official historical books, local chronicles, annals and regional meteorological disaster yearbooks. By using moisture index and flood/drought (F/D) index obtained from the above information, the historical climate change, namely wet-dry conditions in borderland of Shaanxi Province, Gansu Province and Ningxia Hui Autonomous Region (BSGN, mainly included Ningxialu, Hezhoulu, Gongchanglu, Fengyuanlu and Yan'anlu in the Yuan Dynasty) was studied. The results showed that the climate of the region was generally dry and the ratio between drought and flood disasters was 85/38 during the period of 1208-1369. According to the frequencies of drought-flood disasters, the whole period could be divided into three phases. (1) 1208-1240: drought dominated the phase with occasional flood disasters. (2) 1240-1320: long-time drought disasters and extreme drought events happened frequently. (3) 1320-1369: drought disasters were less severe when flood and drought disasters happened alternately. Besides, the reconstructed wet-dry change curve revealed obvious transition and periodicity in the MongoI-Yuan Period. The transitions occurred in 1230 and 1325. The wet-dry change revealed 10- and 23-year quasi-periods which were consistent with solar cycles, indicating that solar activity had affected the wet-dry conditions of the study region in the Mongol-Yuan Period. The reconstructed results were consistent with two other study results reconstructed from natural evidences, and were similar to another study results from historical documents. All the above results showed that the climate in BSGN was characterized by long-time dry condition with frequent severe drought disasters during 1258 to 1308. Thus, these aspects of climatic change, might have profound impacts on local vegetation and socio-economic system. 展开更多
