Mathematical model analysis of wheatcultvars ecotypes evolution, through the 2005-2006 study of five wheat-522 samplesof wheat Ecological Survey, take hypothesis testing statistical methods to the analysisof the regional differences were significant problems 1 while wheat cultvars, and late-maturing varieties of early maturing varietiescan not meet the needs of production, gradually been eliminated, while early varietiesto be preserved.

本论文研究主要结论有： 1、在品种更替过程中，早熟品种和晚熟品种所占比例分别由80％和30％降低为零，两种生态型逐步遭到了淘汰，而中早熟品种得到了保留，由1978年的零分布增加到2005年的46％。 2、偏春性和冬性品种分别1988年至1996年和1991年至1993年和的变化较大，其动态变化度分别为1和0.66。

Higher Ca distributed in bulliformcell than in mesophyll cell and bundle sheath cell of dune reed, higher Mg distributedin mesophyll cell and higher K, Na and Cl distributed in sheath cell HigherNa and Mg distributed in mesophyll than in bulliform cell and bundle sheathcell of light salt meadow reed, and higher K, Ca and Cl distributed in itsbundle sheath cell. Higher Na and Mg distributed in bulliform cell than in mesophyllcell and bundle sheath cell of heavy salt meadow reed, higher K, Ca and Cl distributedin its mesophyll cell. This paper discussed the distribution conditions of theabove five ions in leaf cell of the four reed ecotypes and the meaning ofphysiological adaptation to habitat in detail.
