储存原始数据后，将其在R中命名为test，运行以下数据就能得到你要的条形图了

tp <- barplot(test$Length_distribution, names.arg=test$Sequence_size, las =2, ylim=c(0,30000),col="black")

text(tp, test$Length_distribution, labels =test$Length_distribution,pos=4,srt=90,offset=0)

x<-c("北京","天津","河北","山西","内蒙古","辽宁","吉林","黑龙江","上海","江苏","浙江","安徽","福建","江西","山东","河南","湖北","湖南","广东","广西","海南","重庆","四川","贵州","云南","西藏","陕西","甘肃","青海","宁夏","新疆")

y<-c(58.81,11.16,439.33,284.41,2487.90,557.31,763.87,1962.13,6.81,162.10,601.36,380.42,801.27,1001.81,254.60,39.07,713.86,1011.94,906.13,1342.70,187.77,316.44,1703.74,653.35,1914.19,1471.56,853.24,507.45,406.39,61.80,698.25)

barplot(y,names.arg=x,xlab="省市",ylab="森林面积(万公顷)" )
