| Abstract: | Aiming at the internal contradictions and external factors which affect the population-economy pressure,we confirm evaluation indicators.The principal component analysis is adopted to calculate the population-economy pressure index.we an-alyze quantificationally the population-economy pressure in Shiyang River Valley.The result shows that the Spatial pattern of the population-economy pressure in the Shiyang River Valley assumes semi-circular structure.This paper studys the popula-tion-economy pressure of all these counties in the zone and provided countermeasures. |
