Abstract One philosopher had said:"it is impossible that we understand the nature's secret before understanding the human nature's secret." For this reason, this paper tried to study the relationship of the man-land system from the show of connotation of human nature. Based on the analysis characteristics of "the two laws self-backing" of human nature, the writer had recognized the human nature connotation in the 4 aspects. ①the relation between cultural man and land; ②the mankind contradiction by themselves is the fundamental cause of the existence of man-land relationship contradiction; ③ the characteristic of human nature decided by the living attitude; ④the serious consequence because of overlooking human nature research. Finally, through analyzing the interaction of human nature and technology, the author points out that the human nature essence connotation would be introspection-way, so call " to be self-created", but not to lose human nature in the process to seek matter boundlessly. The tentative ideas of human nature molding and regression had been raised in the end.
This researching consequence gives us the clear inference that human nature connotation must be molded and renewed. From the history, human nature connotation had experienced the 4 aspects that contains:man is restricted by nature (barbarous period)、man is to receive instructions from nature (agriculture revolution period)、man can conquer nature (industrial revolution)、man and nature combine as one part (today). The Writer thought that introspection-way of human nature molding is a healthy, safe, ideal living mode. It is also the scientific express of human nature in the man-land relationship. Mankind needn't practice usury and exploit the earth to create wealth or fortune and to seek happiness, mankind may fully conform to the nature with probing to nature's mystery, and according to the land's regularity to utilize and change it.
