我在这里发现，食草哺乳动物的种群密度与生物量，堪与状况最好的东非大草原地区相比。

I determined that densities and biomass of herbivorous mammals in Nagarahole were comparable to some of the best East African Savannah areas.

平原地区一般河网密度高，河道比降小，水流流泄不畅，极易造成内涝灾害。

In the plain area, because of the channel density is large and the slope of riverbed is small, the channel flow is slow and the waterlogging often occurs.
