The vegetation patte in the upstream of Minjiang River,and its relationship with environment factors,such as landscape position(elevation,slope,aspect),precipitation and temperature and soil are analyzed in this paper.The data used in this Paper were based on the landscape map derived from 1994 TM imagery.The results were as follows:1)dominant landscape types were forest,shrub land and grassland,which were very similar in terms of area ratio(32.87%,31.85% and 28.44%,respectively);2)the patch shape of conifer forest and mixed forest was complicated while that of broad-leaved forest and cultivated land was simple;3)the fragmentation of conifer forest and mixed forest was serious in contrast with low fragmentation of broad-leaved forest and cultivated land;and 4)closed scrub and grassland had a high contagion and good connectivity while mixed forest had a lower contagion and bad connectivity.In addition,the vegetation distribution patte of upstream of Minjiang River Was closely related with elevation and temperature,but the relationship between vegetation and precipitation was not statistically significant.

内容摘要：本文主要论述美院公共艺术课程教学的方法、特点、目的以及评判标准，认为公共艺术课程在开启学生智慧、激发创造性思维的同时应当进行跨学科跨领域授课，并认为“意境”是评判课程的标准。 关键词：公共艺术课程 学科建设 意境 公共艺术是近年来新兴的一门学科，公共艺术的产生和发展是与我国城市化建设紧密联系的，城市的勃兴推动公共艺术的发展，也对公共艺术的发展提出新的要求。正因为“新的要求”，所以
为了解油菜、马铃薯间作及磷肥施用效应,油菜采用中油杂11号,马铃薯采用南中552为供试材料,在大田种植条件下,研究了间作和磷肥用量对两种作物产量、对油菜生理特性、以及对油菜养分吸收利用特点和土壤养分含量变化的影响,试验结果如下:1对产量和农艺性状的影响不同行比间作油菜产量以T2-1:3-P3最高。各间作处理油菜单位面积角果数和千粒重均高于单作处理,而每角粒数较对照均有所降低。间作处理植株株高均比单

本试验以桂糖40和柳城05136为供试材料,在广西南宁市宾阳县廖平农场进行甘蔗机械收获和甘蔗人工收获试验。在甘蔗生长的不同时期分别研究两个甘蔗品种机械收获对宿根蔗生长、甘蔗农艺和产量性状、土壤理化性状、根际土壤酶活性和根际微生物群落结构的影响。实验结果如下:一、不同品种甘蔗机械收获处理的碾压会导致蔗地土壤容重增大和土壤含水量减少,但随着甘蔗的生长和开垄松蔸,土壤容重和土壤含水量的差异越来越小。机械
