The paper, taking Songliao Plain for example, studied the concept, distribution law and formation mechanism of inland saline alkaline wetland. The inland saline alkaline wetland is distributed over the inland region of arid or semi arid climate; it is the wet or slightly stagnant environment, forming saline alkaline soil and salt vegetation and making the geogra phical environment fonming complex with an ecosystem of saline alkaline wetland. The laws of zone nature and non zone nature control the distribution of the inland saline alkaline wetland that extensively spreads in north part of china and other countries. The inland saline alkaline wetland is formed jointly by atmosphere, hydrosphere, lithosphere and biosphere including intellectual sphere. Under the special condition, the artificial activity is possibly the key function. In order to improve the human environment, it is a great duty confronting the whole world to rationally transform the inland saline alkaline wetland. Therefore, we presented an anti inland theory to promote the environment transformation.

＜正＞The economic system of mining city is of typical vulnerability characteristics that can be manifested by its high economic sensitivity and lack of response capacity to the gradual depletion of regional mineral *** Fuxin as the case city,this paper established a economic vulnerability assessment method integrating BP neural network and vulnerability index,then carried out an economic vulnerability assessment of Fuxin during 1989-2.06,the results indicate that:①Affected by the gradual depletion of regional mineral resources,the economic development of Fuxin had kept high economic sensitivity from 1995 to 2.01,the response capacity to cope with and adapt to the impacts of the perturbation was weak and relatively lag,the evolution of economic vulnerability can be divided into three variation stages;②The influence of economic sensitivity on Fuxin economic vulnerability is more evident than the influence of response capacity;③The decreasing supply of mineral resources and the simple industrial structure are main factors leading to the economic sensitivity of Fuxin;④The improvement of economic response capacity of Fuxin is of typical input-driven growth characteristics,external assistance is of great importance to rapid improvement of economic response capacity of Fuxin;⑤Diversification of simple industrial structure of Fuxin is still unaccomplished,the contribution of non-coal-based industry to local economic development is relatively limited.

Rock phosphate （RP） is a low efficiency P fertilizer that is directly applied to the soil and can be solubilized by phosphate-solubilizing microorganisms （PSMs） in fermentation or soil conditions. This study investigated dynamic solubilization of 2.concentrations of rock phosphate in a liquid culture with different dosages of glucose by two fungal isolates,Aspergillus niger P39 and Penicillium oxalicum P66, from soybean and wheat rhizosphere soil. Although during the 2. day culture period A. niger P39 had a stronger ability to acidify the culture media than P. ozalicum P66, soluble P concentrations at glucose dosages of 30 and 50 g L^-1 with RP of 15 g L^-1 in the culture solution were much higher by P. oxalicum P66. The greater effectiveness of P. oxalicum P66 compared to A. niger P39 in the solubilization of RP was strongly associated with the production of organic acids. This study suggested that for RP solubilization the type rather than the concentration of PSM-produced organic acids was more important.

Based on the data of wetlands in Huanghe delta and Liaohe delta which were go by the combination of Remote Sensing(RS), Geographical Information System(GIS) and Global Position System(GPS), the paper discusses the sindlarities and differences of wetlands in the two regions by comparing them in composition, distribuhon, spatial pattern of landscape and ecology. Problems in using and conserving weiland resources are shown in the paper, which aimto provide basis for the further study on the landscape ecology, function, and sustainable use of weilands in the deltas. The study shows that the wedands in the two deltas are characterized by peat variety of weiland types, distribution with the shape of strip, abundant resources of wild plants and animals, intense effects of human activities on the structure of the landscapes, broad prospects for development and great environmental pressure. It is necessary to successfull solve the contradiction between development and protection. At present, the most pressing matter of the moment is to protect environment and control pollution.

The relationship between humic acid and selenium content was studied in this research. The results of calculation showed that there is more humic acid and less selenium in Kaschin-Beck disease areas in china. Fulvic acid in soil could increase selenium level in plants. The chemical bonding between humic acid and selenium was observed with an I.R. spectroscope. It was remarkable for the changes of absorption peak and frequency in 1100-1000 cm-1, 900-700 cm-1.

Through statistical analysis on data of atmospheric precipitation samples of 8 cities from 1992.to 1997,this paper discussed temporal and spatial variations of pH in atmospheric precipitation in Jilin Province, china Monitored pH value in the 8 representative cities was converted into hydrogen ion consistency and average condsistency was calculated by weighting precipitation, then mean pH value was calculated according to average hydrogen ion consisteney. Results show that atmospheric precipitaion of cities in Jilin Province is basically. neutral, but in Tumem and Hunchun cities atmospheric precipitation is seriously acid. The average pH value of atmospheric precipitation of the eastern cities of Tumen and Hunchun in many years is 5. 12.and 5. 38 respectively, and the atmospheric precipiboon acidity in the two cities is quite serious with the extreme low pH is 3. 91 and 4. 2. respectively. Most of the acid precipitation occurred in summer and autumn seasons in the 8 monitored cities, so that the low pH value of atmoopheric pmeipitation occurred in summer and autunm seasons and high pH value occurred in winter ed spring seasons. The temporal and spatial variations of pH in atmospheric precipitation in Jilin Province are attributed to both local sources and peripheral sources, and are related to both natural and artificial factors.
