论述我国土壤水平地带性分布规律

答案

参考答案:

我国土壤水平地带性分布规律主要受水热条件控制。在秦岭—淮河以南地区属亚热带至热带,由于受湿润季风的影响,热量和雨量自北向南递增,土壤带基本上随纬度变化,自北向南出现黄棕壤、红壤和黄壤、砖红壤性红壤和砖红壤。

上述我国东部土壤地带性分布规律基本上与纬度带相一致,即由南而北依次为砖红壤—砖红壤性红壤—红壤—黄棕壤—棕壤—暗棕壤—灰化土。

温带地区的经度地带性由东往西为:黑土、白浆土、黑钙土、暗栗钙土、栗钙土、淡栗钙土、棕钙土、灰漠土、灰棕漠土;暖温带地区的经度地带性由东往西北为:棕壤、褐土、黑垆土、灰钙土、棕漠土。

Dear Mum:

Today I’m going to tell you something really special. I know you work very hard and feel tired every day.

Every time you come home and see the messy(杂乱的) house. I know you are very angry with me. But you always say nothing and clean up the house .I always want to help you, but I have so much homework to do. After I finish my homework, I feel like dying. I really want to help you, but I’m so tired too.

I also want to tell you one thing, I love you so much. I usually talk back to you when you say that I don’t study hard enough. But in fact I just want you to praise(赞扬) me more. I will try my best to get good grades and get praise from my teacher. So don’t feel frustrated (失望)about my grades, OK? I have made up my mind that I will study harder and help you to clean the house. I am serious this time. I will have my homework done faster so that I can have more energy to clean the house. I will watch TV less so that I can have more time to study and get good grades. All these things are for one reason: I want to make you happy Mum.

I love you!

With lots of love Sally
