Through field observations and sampling, by referencing to other documents and information, with correlation analysis and principal component analysis as mathematical tools, we know that: the distribution of the number of birds has close relations with density of zoobenthos and ratio of water area, the correlation coefficient of the distribution and the two factors are 0.916 and 0.745, the density of zoobenthos is the most direct reflection; Vegetation types , the coverage and water level may have relations with the distribution of the kind of birds, normally, middle and large volume birds need high vegetation and high coverage as their habitats, and waterfowl like deep water as their habitats; Human activities have low impact on the the distribution of the number of birds, but the activities have relations with all the other environmental factors.
通过实地的观测、采样,并结合其他文献的资料,以相关分析和主成分分析作为数学工具,得知:鸟类的数量分布和底栖生物密度、水域面积比例有着密切关系,鸟类数量分布与两者的相关系数分别为0.916和0.745,其中,底栖生物密度是鸟类数量分布的最直接反映;植被类型、植被盖度和水位可能与鸟类的种类分布有一定关系,通常体积中、大型的鸟类需要较高的植被高度,来作为自己的栖息场所,水禽需要水位较深的区域作为自己的栖息场所;人为活动对鸟类数量分布的影响不大,但对所有自然环境因子都有一定影响。

The biological hydrogen is very important to solute the energy crisis and the environmental pollution. Our country works out the organic waste water zymotechnics biological hydrogen technology by the tired of oxygen active sludge and the organic waste water as produces raw material. It is proved by the experiment in HIT. This research was discovered first in our country and foreign and realized the experimental scale non-fossilization mold mushroom spawn for a long time to continue producing the biological hydrogen technology. It also realized the experimental scale continue to produce the hydrogen for a long time. It was a domain significant breakthrough in biological hydrogen.

Thermal characteristics of salty soil are researched by TG-DSC technique. The results show that soluble salts have great influence on thermal characteristics of salty soil; water content gets higher, phenomena gets acuter. Freezing force depends on water content and freezing temperature; the more water content or the less temperature is, the more intensive of freezing force is.
