能不能举例说一下如果要表达达到限制很多年，应该怎么说呢？能用SINCE么？我真的弄糊涂了·····拜托拜托啦~！

Just google, and find the answer below:

since后如果接短暂性动词，表示的是否定的意思；如果接延续性动词则表示肯定的意味。

如：
It was 10 years since they married.可译为：他们结婚已经十年了。

It is two months since he was ill.可译为：他病好已经两个月了。

It is two months since he fell ill.可译为：他病了已经两个月了。

Seems the issue escalates:-)

Since can function as a conjunction linking two clauses together, as in ‘I’ve known Joanna since she was born’ or ‘I hadn’t seen her since she went to live in Oxford’. In such cases it is normally used with the present perfect or past perfect tense, either in the simple or continuous form.

As in the present case, It has been many year since the last time the hunting season was closed early. Did the hunting season close early last year? The year before the last?  And why?

看来皆是个纠结的帖子···我想说我还是不太明白···

Well, it is a rather simple case.

If the hunting season was not closed early last year, that means the loss of the geese was below 5% of their population due to hunting.

Then if you remove the restiction of "only 5% of geese can be shot down each year," what kind of effect would you have on the geese population?

Nothing! Because the same hunters would show up and shot down the same number of geese - less than 5% of the total, just like what happened last year.

这个我懂了····我是说关于since 的用法不懂····就语法来说的~

Then see #14's explanation.

It has been many years since the park was closed early than scheduled. Did the park close early than scheduled last year? The year before the last?

In terms of grammar, It has been many years since (an event happened at a time in the past), simply means the time that event happended was a long time ago.
