Abstract: Based on the land use analysis model of PS123, the simulation of soil salts effects on crop growth is integrated in PS123 model con sidering osmotic stress of the salt effects on water uptake and production. This salt integrated crop model is more suitable to be used in salinity land and wa ter irrigation simulation. This model is calibrated with field experiments condu cted at Hebei Quzhou Experimental Station of China Agricultural University. But there are still some problems to be solved such as the simu...

Abstract: The study was conducted in Huantai County Shandong Province in North China to study the secondary succession of earthworm population under low and high soil fertility in agro-ecosystem. The result shows that seven species were found both in two agro-ecosystems, but the earthworm population density and composition are different, the average earthworm population in the high fertility soil is relatively abundance, the population density is 83.83 in./m~2. Among the seven earthworm species, Aporrectae trapezoids is the dominant species. While in the low fertility soil, the population density is 40.18 ind./m~2 and Drawida gisti is the dominant species. Comparing the density of each earthworm species in the two kinds of soil fertility agro-ecosystems, the density of Aporrectae trapezoids and Amynthas hupeiensis is significantly higher in the high fertility soil than that in the low fertility soil, while the difference of other five species is not obvious. This result shows that with the succession of the soil fertility, the earthworm also has a process of succession; the abundance species in the low fertility agro-ecosystem Drawida gisti is gradually substituted by Aporrectae trapezoids in the high fertility agro-ecosystem. One-year experiment was also conducted to study the impact of the organic input on earthworm population and succession. The result shows that with the increase of the organic input, the earthworm population density is increasing, the earthworm density of the treatments has the following ascending trend: Chemical fertilizer

Abstract: After the calibration, the land quantified model (PS123) is used to analyze several factors of land use system such as the sealing date, irrigation scenario and biophysical potential production. The optimum seeding date is from the end of September to October. The irrigation amount is 180 - 240 mm and it is appropriate to irrigate 75 - 90 mm each time at the last part of the growing season. The biophysical potential yield of Quzhou region is about 11010kg/hm2 .

Abstract: Ozonation and biologically activated carbon process, one of advanced treatment technologies, has been applied in many places at home and abroad. However, some emerging water quality problems appeared in operation. Drinking water treatment plant (6×105 m3/d) with ozonation and biologically activated carbon process (O3-BAC process) was investigated systematically, including microbial safety, the excessive growth of aquatic microorganism and chemical stability of water quality. And some experiments were done in the pilot plant (10 m3/h) at the same time. O3-BAC process is reliable in microbial safety, but operation management should be enhanced. A good number of aquatic microorganisms grow immoderately during operation of O3-BAC process, which is more serious especially in place with high temperature and humidity. With prolong of runtime, the growth of aquatic microorganisms varies regularly. That is hazardous to water quality safety. When raw water is low with alkalinity, decrease of pH in O3-BAC process is obvious. That will seriously affect on chemical stability.

Abstract: Tengchong volcanic geothermal area is located at the active arc zone of the subduction and collision of the Indian plate and Eurasian plates, and is considered as one of the most potentially active volcanic eruption areas in China. In order to study the spatial distribution and activity of the underground magma chamber, MODIS LST (Land Surface Temperature) data were used to identify the geothermal anomalies that may be created by the heating from the underground magma chamber. The monthly night MODIS LST data from Mar. 2000 to Mar. 2011 of the study area were collected and analyzed. The 132 month average LST map was derived and three geothermal anomalies were identified. In the light of the previous studies in this area, it can be deduced that there are three magma chambers beneath the three thermal anomalies. The first one is located along Wuhe-Xinhua-Puchuan-Tuantian with the most significant geothermal anomaly, and covers 537km2. The second one is situated in the Langpu-Rehai-Maanshan area with a significant geothermal anomaly and an area of 226km2. The third one is located between Mazhan and Qushi with an obvious geothermal anomaly and a coverage of 28km2. It is also found that the patterns of the monthly LST variation of the three thermal anomalies are similar, with 2 temperature peaks occurring in May, June and August, September, which is different from that of the local temperature of the same period. The 10-year annual LST of the geothermal anomaly in Langpu-Rehai-Maanshan area shows the greatest variations among the three, which suggests the active convective exchange of heat between the underground magma chamber and the surface water, and can be inferred that the beneath this magma chamber is the most active among the three. The findings of this study agree well with the results from seismology, GPS-based deformation detection, He isotopic emission and relative geothermal gradient measurements. It demonstrates the effectiveness and potential of thermal infrared remote sensing in geothermal studies.

Abstract: 以赤子爱胜蚓(Eisenia fetida)为试验动物, 选取氯化镉、马拉硫磷和乙草胺作为污染物, 通过人工土壤法研究了3种污染物在5种比例两种污染物复合条件下对蚯蚓的急性毒性。研究结果表明, 3种污染物在两两复合污染时的作用类型以拮抗为主, 仅在镉浓度19.46 mg·kg-1和乙草胺175.15 mg·kg-1 (1︰9)复合类型是相加作用, 说明复合污染生态毒理效应与污染物的化学性质和浓度水平均相关。从蚯蚓活体体重减少情况看, 在复合污染条件下, 污染物对蚯蚓生长的影响与单一污染的结果类似, 马拉硫磷对赤子爱胜蚓的影响最大, 乙草胺次之, 而氯化镉的影响最小。

Abstract: The study was conducted in farmland with low productivity in Huantai County, Shandong Province of China North Plain to study the impact of organic manure and chemical fertilizer application on earthworm population. The result shows that there are 3 families, 6 genera and 7 species. Drawida gisti is the dominant species. The seasonal variation of the earthworm population density has following trend: August> September>April >May>November. The chemical fertilizer increased the earthworm population compared with the control treatment in the low soil fertility agro-ecosystem. The impact of fertilizer on the earthworm population depends on the input of organic material. With the increase of the organic input, the earthworm population density is increasing. The earthworm density of the treatments has the following ascending trend: Chemical fertilizer
