[Method] Adopting questionnaire survey and analyzing the differences of tourism facilities. [Result] The overall satisfaction of tourists in tourism facilities is 47.2%,a basically satisfying level; the least satisfaction level is 31.8% in public sanitation facilities after the satisfaction in recreation and explanation facilities. [Conclusion] With experiencing the ecology and returning to the nature as characteristics,the construction of facilities should comply with the theme of agricultural tourism to demonstrate the characteristics of agriculture and the local area,and in the scale of planning,architectural style and subject selection also should follow this principle. Investigations about the tourists resources should be carried on,the construction and management of transportation,greening and public sanitation facilities should be proceeded effectively to attract tourists to stay or come again and to realize the sustainable development of agricultural tourism.展开更多

The results show that the Jiangsu area is a high Q value area as a whole,but the Q value differs obviously between different regions,characterized generally as high in the south and low in the north. This study focuses on 4 sub-regions where the stations are relatively dense,the tectonic features are distinguishing,and the calculation results of coda Q0 are fairly concentrated,and obtains the characteristic relationship between the Q value and frequency of the 4 regions. The region from south Jiangsu to the Yangtze River estuary and that around the Maoshan fault zone are the high Q value areas in Jiangsu; the region from central Jiangsu to the waterfront area is the low Q value area in Jiangsu Province,and the Lianyungang region in northern Jiangsu is the moderate Q value area. Comparing the tectonic activity and seismicity of the 4 different Q value sub-regions,there is a certain correlation between Q value,crustal movement and seismicity.展开更多

Taking the southern Jiang-su Province area as an example the orientation measurement of quartz crystals, the com-positional texture observation of three pressure sensitive minerals and the rheological param-eter determination of dislocation densities, etc. have been demonstrated and analysed basedon typical samples in the present paper. In addition, their generation mechanisms arealso discussed from the cataclastic rheology, the dynamic differentiation and the simpleshearing, specially, from the Ode strength theory. Finally, a generative relationship betweenthe ductile deformation domain of the brittle fault system, in the regional layer--slip andthe formation of the stratabound ore deposit is shown as well.展开更多

Through typical survey,this paper made an objective evaluation of effect of agricultural comprehensive development of hilly and mountainous areas in Jiangsu Province from increasing farmers' income. Results indicated that agricultural comprehensive development investment projects in Jiangsu hilly and mountainous areas are closely coupled with local agricultural production structure; financial funds promote social capital input to construction of economic forest,fruit and grass planting,and livestock raising. Through demonstration and guidance of farmers,it promoted adjustment of agricultural production structure and increased farmers' income. Finally,it came up with pertinent policy recommendations.展开更多

By comparing the tsunami data from Guanhekou marine station with other tsunami wave observation gathered from southeast coastal area of China, it was evident that, only in Guanhekou, the position of the maximum wave height appeared in the middle part rather than in the front of the tsunami wave train. A numerical model of tsunami propagation based on 2-D nonlinear shallow water equations was built to study the impact range and main causes of the special tsunami waveform discovered in Jiangsu coastal area. The results showed that nearly three-quarters of the Jiangsu coastal area, mainly comprised the part north of the radial sand ridges, reached its maximum tsunami wave height in the middle part of the wave train. The main cause of the special waveform was the special underwater topography condition of the Yellow Sea and the East China Sea area, which influenced the tsunami propagation and waveform significantly. Although land boundary reflection brought an effect on the position of the maximum wave height to a certain extent, as the limits of the incident waveform and distances between the observation points and shore, it was not the dominant influence factor of the special waveform. Coriolis force's impact on the tsunami waves was so weak that it was not the main cause for the special phenomenon in Jiangsu coastal area. The study reminds us that the most destructive wave might not appear in the first one in tsunami wave train.展开更多

Traditional villages in coastal area are the important carrier of sea salt culture, reflect a unique human landscape, form the unique structure characteristics and become China’s rural society’s important component. But in recent years, due to the urban renewal and the accelerating of the socialism new rural construction and the deterioration of the natural environment, traditional villages in Jiangsu coastal areas relying on the natural and cultural environment are experiencing an unprecedented test. In this paper, according to the investigation of the coastal areas of existing traditional village, after the comparative analysis, some basic spatial structure characteristics were summarized. It is expected to provide a reference for the planning, construction and management of villages.展开更多

[ Method ] TO enhance the ability of meteorology to service laver culture, using the modern weather forecast technology, agricultural weather prediction was de- veloped according to the demands for meteorological conditions during laver production. [ Result] From south to north, there were certain differ- ences in the suitable periods of laver culture, breeding and harvesting, with slight variations. The forecast of the first and last days of certain water temperature could provide scientific references for the meteorological service of laver culture, and the service effect became better after it was modi- fied with the aid of the medium-term and long-term weather prediction. [ Conclusion] The research can offer theoretical bases for the culture of laver along the coastal areas of Jiangsu Province.展开更多

We find that the frequency-dependent Q in the Jiangsu region is Q( f) = 272. 1·f^(0. 5575). We also use Moya's method to invert the 63 stations' site responses. The results show that the site responses of the 25 stations in Jiangsu are approximately 1 at a range between 1Hz and 20 Hz, which is consistent with their basements on rocks. The response curves of the site responses of the 14 underground stations are similar to each other. Their site responses show an amplification at low frequencies and minimization at high frequencies. The calculation of the Brune model on the waveform data of M_L≥2. 5 earthquakes from Jiangsu Digital Seismic Network between October 2010 and May 2015 in terms of seismic source parameters of 58 seismic waves shows that there are good correlations between seismic magnitude and other source parameters such as seismic moment, source radius and corner frequency, while the correlations between seismic magnitude and stress drop,and stress drop and source radius are not so good.展开更多
