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。

RESULTS: NK cells represent a unique subset of lymphocytes that have no restriction by MHC antigens and have the ability to lyses certain tumor cells without the requirement for prior immune sensitization of the host. In addition, NK cells can also produce cytokines and regulate the function of other immune cells. So, it is emerging to apply NK cells as therapeutic agents against a broad range of malignancies. In this respect, the anti-tumor activity of NK cells is the key factor of NK-cell-based immunotherapy.

结果：NK细胞是一种独特的淋巴细胞，对靶细胞的识别无MHC限制性，无需预先致敏即可直接杀伤肿瘤细胞，也可分泌细胞因子调节其他免疫细胞的功能，是机体天然免疫的主要承担者，也是获得性免疫的核心调节细胞，故NK细胞在抗肿瘤免疫中的地位越来越受到重视，随之增强NK细胞肿瘤杀伤活性的研究也逐步深入。
