In your scenario, assuming you mean the aircraft is 2000' above the airport elevation at almost 1 nautical mile from the runway, the descent rate required would be almost 6X greater than normal... 3 degrees is the normal descent angle.

Thank you.
Should I understand that 3 degree angle having a bearing of about 5 miles after another prior drop?
I check a few US inland airports (like San Jose) and found they
have very short distance between first obstruction to the landing threshold. Some Google seach shows 1.5NM (~12000 ft) distance.
My specific location has only 900m (2900 ft) between airport fence and landing edge, which yields an altitude of 155' high at the fence (~ 15 story high building).
I wonder if it's practically possible for windward landing. (I am having a 2.6km landing strip at this moment).

Normally one plans 300' AGL per mile, add another 40-50' for threshold crossing. That leaves us at 950' 3 miles out, with a normal 750(+/-) VSI.
Of course rates of descent can be adjusted within reason to correct. If things get towards the crazy side we end up with an 'unstabilized approach'. The severity could be slightly, to the other ending with bent metal.
Some things aren't meant to be done within the normal operating envelope.
