The results show: the most sensitive Chinese area to acid deposition is Podzolic soil area, then follow Latosol, Dark brown forest soil and Black soil areas; Ferraisol and Yellow-brown earth area in southern China can buffer about 0.8-1. 6 g Sm〓yr〓 sulfur deposition; the least sensitive areas to acid deposition are mainly Xerosol area in northwest China, Alpine soil area in the Qingzang Plateau, and Dark loessial soil and Chernozem areas; the main reason for lower critical load in northeastern areas and higher critical load in Ferralsol and Yellow-brown earth areas in China can be attributed to the obvious difference in temperature, humidity and soil properties.

研究表明：我国土壤对酸沉降最敏感的区域是漂灰土带，其次是砖红壤土区、暗棕壤带和黑土区，南部富铝土区域大致可接受O.8-1.6 g Sm〓yr〓的硫沉降，对酸沉降最不敏感的区域主要集中在西北干旱土和青藏高原的高山土区域以及黑垆土和黑钙土带；导致我国东北地区酸沉降临界负荷偏低和富铝土区域酸沉降临界负荷偏高的重要原因，是这些地区的气温、湿度和土壤质地存在显著差异。

Fluorine is one of crucial chemical elements to human health and can be tested in almost every parts of a healthy human body. Overloading of fluorine may cause dental and/or skeletal fluorosis, while in fluorine deficiency areas, fluoride drinking water supply or other methods of fluoridation may greatly reduce the ratio of dental caries of local residents. Researches on relation between fluorine concentration in drinking water and the ratio of human dental caries as well as the evaluation on efficacy of drinking water fluoridation have been lasted for 6 decades.

For the 12 yearold children, the prevalence, SiC index and DMF index showed markedly higher in industrial areas than in nonindustrial areas. Still more, the dental fluorosis index was near the epidemic.The oral plaque index demonstrated lower in the industrial areas than that in nonindustrial areas.The fluoride concentration in drinking water was under the national criterion in both areas(1.0 mg/L).

Labeled perforin cDNA probe in liver biopsy tissues. RESULTS: Perforin positive cells were seen in the whole intralobular areas, especially in inflammatory areas. The amount of positive cells was different, 71.9% in spotty necrosis areas, 31.0% in focal necrosis areas, 9.2% in portal areas and only 4.8% in non????

The amount of positive cells was different, 71.9% in spotty necrosis areas, 31.0% in focal necrosis areas, 9.2% in portal areas and only 4.8% in non necrotic areas. The average amount of perforin cells in the liver lobules of 18 patients had no linear correlation with the ALT level or Knodell's histology activity index.

The research applied landscape ecology, integrating land using, ecology networks, and the concept of human needed environment model addressed by Odum to build natural and cultural criteria which are used to decide natural factorsand cultural factors. Subsequently, applying the criteria and planning procedures to category land into agricultural and non-agricultural areas. The agriculture areas include basic grain production areas, and leisure agriculture areas. The non- agriculture areas include agriculture of river corridor ecology restoration areas and remnant cultivates lands. Above all, remnant cultivated lands are separated into wilderness, parks or indefinite areas because of different context.
