In Shanghai, three trades including water conservancy, water supply and water drainage are managed integratively by Shanghai Water Authority. However, trade division is apparent among them, and information sharing needs to be strengthened. Therefore, lack of information standard is becoming an urgent problem to be solved. According to the strategic objectives of "Golden Water Project" in China and "Digital City" in Shanghai, "Shanghai Water Management Information Standard" is made for normalizing information classifications, codes, terms, GIS symbols and attributed data structures. It not only coincides with national standards, ministerial standards and Shanghai local standards, but also embodies the characteristic of integrated water management in Shanghai. It provides "traffic rule" for resources integrating and information sharing. Some good research ideas such as omni-direction, multi-levels and facing application can be popularized in other provinces and municipalities of China.

In order to understand the type and extent of marine fouling in offshore areas southeast ofthe Zhujiang (Pearl) River delta, within the period form May 1986 to June 1987, two biological buoys were deployed at water depths of 95 m and 113 m located in 114 km and 160 km off the coast of Hong Kong, respectively. Moreover, the fouling community of a Marex hydrological buoy located in 115 m depth water 172 km off Hong Kong was also surveyed. The results show that a total of 78 species were collected and identified. The panels exposed for 3 months were mainly dominated by stalked barnacles Conchoderma hunteri and Lepas anatifera and hydroids Orthopyxis sp. As for the buoys, including the subsurface buoy, and their mooring systems exposed for 6 and 12 months, respectively, some hard foulers such as common oysters, pearl oysters, acorn barnacles and bryozoans were also found. The compositions of fouling communities also varied greatly with depth.

This paper reports the species composition and distribution of fouling bryozoans in the northern SouthChina Sea. 34 species identified belong to 23 genera, 22 families of fouling bryozoa, of which most of 24 species on thebuoys attached to concrete sinkers. The 13 species on platforms mainly included Schizoporella errata and Membranipora savartii. Depth distribution of species, larval settlement behaviour and larvae type of fouling bryozoa are discussed.

Leaf early senescence caused by nutrition deficiency is one of the major limitation reasons in the world crop production. Potassium (K) is one of important nutrient elements in crop growth, which modifies dozens of enzyme activations and controls stomatal movement of photosynthesis. The yield and quality of maize (Zea Mays L.) have been limited due to K deficiency in plough layer soil. However, the mechanism of K deficiency tolerance is not fully understood in maize. In this study, two inbred lines, 099 (tolerance to potassium deficiency) and 835 (sensitive to potassium deficiency) were carried out to investigate the variations of chlorophyll content, photosynthetic and chlorophyll fluorescence parameters related with senescence under different K+ concentrations in maize at seedling stage. The results showed that the Chlorophyll a, b and (a + b) of 835 were significantly decreased under different K deficiency treatments, whereas those of 099 were remained normal. In addition, 099 showed a lower stomatal restriction and higher electronic transition capacity under different K deficiency treatments. The variations of F0, Fv/Fm, ΦPSⅡ, qP and NPQ in 835 were largely higher than those in 099. These results indicated that the inbred line 099 tolerance to K deficiency could keep chlorophyll content to maintain photosynthesis and to alleviate the injury of PSII under K deficiency condition. This study should contribute to explaining the physiological mechanism tolerance nutrition deficiency and improving breeding program in maize.
