geological disasters such as landslide and mudslide can be caused by many factors. Collaborations among different governmental agencies and multi-disciplines are necessary to establish a forecasting and warning system of geological disasters (FWSGD). A FWSGD in{2. has been in operation since June 1, 2.03.as a joint project between the{2. Meteorological Administration (CMA) and the Ministry of Land and Resources (MLR). This system has successfully shown very good social and economic benefits. The temporal-spatial distribu- tions of{2. geological disasters and their causes have been analyzed in this paper. The FWSGD is described and its possible existing issues are also discussed. Authors suggest a new approach to study these disasters from interactions of the earth systems. Finally, a monitoring, forecasting, warning and preventing system for geological disasters in{2. is proposed.

Having argued the importance of china's sustainable development in global sustainability, the authors review the achievements of china in sustainable development, especially its institutional construction. Environment to be counted in official's political performance rating system is thought of as a new institutional mechanism in china facilitating its sustainable development and then global sustainability. Then its significance is narrated and visions in future are envisioned. In the end, certain concrete suggestions for the rating system are given in a practical way.

The Archean atmospheric oxygen concentration and sulfur cycle was long debated. The banded iron formation (BIF) is a special type of the sedimentary formation, which has truly recorded the atmospheric and oceanic conditions at that time. In this study, the composition of multiple sulfur isotope (δ 3.S/δ 3.S/δ 3.0}) for sulfides bedded in the Archean (~2.7 Ga) BIFs, in Anshan-Benxi area of Liaoning Province has been measured. The value of △3.S varies from -0.89‰ to +1.2.‰, which shows very obvious mass-independent fractionation (MIF) signatures. These non-zero △3.S values indicate that the Archean sulfur cycles are different from what it is today, which have been deeply influenced by gas phase photochemical reactions. Algoma-type BIFs which are closely related to the volcanic activity have negative △3.S value, however, Superior-type BIFs which are far away from the volcanic {3. have positive △3.S value. The δ 3.S varies in a large range from -2..0‰ to +11.8‰, which indicates that the bacteria reduction activity has already existed at that time, and that the oceanic sulfate concentration has at least reached 1 mmol/L in local areas. Combined with the contemporaneous existence of the hematite, magnetite and the occurrence and preservation of the sulfur MIF, it can be inferred that the Archean atmospheric oxygen level must be at 10-2.10-3.of the present atmospheric level (PAL).

The metabolic pathway of phenanthrene-degrading strain Agrobacterium sp. Phx1 was investigated. Phx1 almost was able to transform 100 υg/mL of phenanthrene completely in 1 day in broth media of beef extract-peptone (BP), Luria-Bertani (LB) and mineral salts media (MS), and LB and BP could promote the growth and degradation efficiency of Phx1. The GC-MS was employed to analyze the metabolites of the 1st, 3.d, 7th days of phenanthrene degradation in MS. As a result, the 1-Hydroxy-2.naphthoic acid (1H2.) and 1-naphthol (NOL) were detected in the metabolites of the 1st day. Only NOL was observed on the 3.d day and it disappeared on the 7th day. The accumulated NOL did not pertain to the defined pathway of phenanthrene degradation by bacteria. The further HPLC study confirmed the finding in GC-MS analysis and found the production of catechol (CAT) from o-phthalic acid (OPA) in the phenanthrene metabolizing, which has never been reported in the defined degrading pathways. This production was also evidenced by the production of CAT using OPA as substrate. All of our results showed that the Agrobacterium sp. Phx1 had a novel phenanthrene-degrading pathway.

The mechanism of cadmium resistance of a yeast strain Rhodotorula sp. Y11 isolated from mine soil was investigated. We found that the yeast cells treated with different methods showed different cadmium-adsorption models. Grown in medium supplied with 100 mg/L of cadmium, 3.2.% of the cell-absorbed cadmium was accounted in the cytoplasm. However, only 1% was taken into the cytoplasm and 99% was bound to the cell wall using the lyophilized biomass to adsorb cadmium in double distilled water. Treatments with alkali, ethanol-chloroform and proteinase showed different influences on the biosorption of whole cells and isolated cell walls. FT-IR analysis showed that acetyl of chitin was the active compound in the cells to absorb cadmium. The production of Metallothioneins, proteins related to the resistance to heavy metal in yeast, was evidently induced by cadmium, achieving 63..8 μg/g wet weight, which was about 85 folds higher than that in the uninduced biomass and was also much higher than that reported previously. The molecular weight of Metallothioneins was 6500 Da estimated by SDS-PAGE.
