摘要：
The decay of virioplankton is one of the most important process of virioplankton population dynamics. Besides the solar-ultraviolet radiation b, other factors can also lead to the decay of virioplankton. Experiment was carried out to study the decay rate of cyanophage PP caused by some environmental factors: non-UVB radiation in sunlight, particle materials, heat-sensitive substances and water temperature. The results indicated that the decay rate of cyanophage PP by the non-UVB radiation part of sunlight at noon was 3.8%.h(-1), however, the decay rate was swiftly attenuated to less than 1.0%-h(-1) with the attenuation of sunlight intensity; in dark condition, the decay rate of cyanophage PP in field sample was steadily 2.5%-h(-1), among which 2.01%-h(-1) contributed to particle materials (in more turbid waters, the number would be as high as 15.0%-h(-1)), and 2.1 %-h(-1) contributed to heat-sensitive substances. The dark decay rate in field sample varied at different temperatures, it was 8.75%-h(-1) at 35 degrees C which was 2.5 times greater than the decay rate at 28 degrees C. Our results suggest that heat-sensitive particle substances are the most important contributing factor to viral dark decay in high eutrophic freshwater and also point to the significance of water temperature in influencing the dark decay rate.

摘要：
During the process of Campus Three Dimensional Visualization Construction using 3DS Max8.0 as the modelling tool, established the campus three-dimensional model of Lanzhou Jiaotong University with the polygon modelling method, substituted traditional paper map with the hypothesized campus, which is much more vivid and intuitive.Realized the ultra link of campus three dimensional landscape and the text and picture with the Virtual GIS extended function module of ERDAS IMAGINE.Campus Three Dimensional Visualization Construction is advantageous in the campus management and planing as well as the propaganda.

摘要：
Ecological footprint analysis is a new method of ecological economics that quantitatively measures ecological consumption by mankind and the extent of sustainable development. Touristic ecological footprint is the application of its theory in tourism research. How to evaluate numerically regional sustainable tourism development is one of significant themes for tourism study. Based on the model of ecological footprint, combined with the ecological consumption and its structure of tourists, this paper leads touristic ecological footprint model into assessment of sustainable tourism, and taking Jiujiang as an example for empirical research. According to these factors, we can provide feasible suggestions for the sustainable development of Jiujiang's tourism industry.

Xiangxi river valley;Climatic resource;Development and utilization
摘要：
This paper discusses the unique climatic resource in the Xiangxi river valley. The features of the climatic resource in the area can be concluded as follows: 1. It is very warm in winter and frost period is short. 2. According to the sea level elevation, the mountains can be divided into several climatic zones. 3. Precipitation is even around the whole year so that rainfall can be used effectively by crops. In addition, it has been found that both topography and meteorological systems result in the features. In order to exploit the climatic resource, some crops for the different heat zones are recommended with the criterions such as under suitable climate condition, high economic value and great market demand. The results suggest that: 1. Below the sea level elevation 500 m is suitable for citrus and tung oil tree. 2. Tea tree and mason pine could be planted between 500 m and 800 m. 3. Mushroom and Chinese chestnut are suitable for the elevation 800 m - 1200 m. 4. The land above 1200 m can be used for forage grass and Chinese medicinal materials. Finally, the hazard of climatic resource utilization and development in this region has also been evaluated in this paper.
