The ascendancy community was Calliphoridae. Herbivore\'s ascendancy communities were Oides decempunctata, predator\'s were Erigonidium graminicola Sundeall, parasite\'s and neutrality\'s were Calliphoridae.3、The seasonal dynamics overall change of community\'s individual numbers, species, relative abundance were basically consistent. All of them conformed to the wavy development trend of increasing -descending-suden increasing-descending-increasing.

The khondalite series within Kongling Group in Yichang City, Hubei Province are composed of aluminum-rich schists-gneisses and garnet-sillimanite-quartzites, leptynite and mafic granulites, its protoliths are clay, sandstones-greywacke and marlite. REE distribution patterns of aluminum-rich gneisses incline NASC, Eu show negative abnormity and Ce displays no abnormity in chondrite-normalized REE distribution patterns.

The best theoretical solution to a partitional clustering problem is to find all possible partitions and choose the partition that minimizes the objective function. However, the enumeration of all possible partitions is impractical even for data sets of moderate size. Therefore, as an alternative, most partitional approaches use an iterative optimization technique. And this could be cause local minimum.
本文在分析了目前聚类的基本方法的基础上,指出以K平均法等为代表的分割聚类虽然理论上找到类的所有划分并使得目标函数最小就可以获得最优解,但由于对于相当尺度的数据集列举所有可能的划分并不现实,因而多数分割方法采用迭代优化技术作为变通。

The main conclusions and outcomes are as follows:(1) From the coupling mechanism of economy and environment, the author appraises the degree of sustainable development in Jinlin province. The results show that the development orientation of Changchun is prone to economic development, for Jilin it is environmental development and for Liaoyuan it is harmoniums development at low level. By quantitative analysis, the author studies the status of sustainable utilization of water resources in this region from three aspects: water supply, drainage and water quality, and the results show that utilization of water resources in each of nine areas that belongs to Jilin province is at low level.
