Taking Heilongjiang Province for an example and using analysis model and grey forecast model
we analyze and forecast the carrying capacity of livestock-breeding environment.Some conclusions can be drawn as follows: The carrying capacity of livestock-breeding environment in the province is strong
but it has appeared a decreasing tendency.According to the present breeding model and the speed of development
the carrying capacity will be below the security line by 2015
if we do nothing for animal excrement.If we take some measures to change 70 percent of animal excrement into energy
feed and fertilizer
the carrying capacity will be below the security line by 2017.For Heilongjiang Province being a big livestock husbandry province with rich natural resources
we should still pay great attention to animal excrement pollution.
