| 英文摘要 | Eutrophication is one of a series of villains hindering economic growth and ecological conservation at various scales. Based on the social-economic statistical data, survey data and the first national pollutant sources census data of Poyang Lake Watershed, the emissions of Total Nitrogen (TN) and Total Phosphorus (TP) of three major industries and ten sub-intermediate sectors were estimated and a Input-Output (10) table was created, embedded with TN/TP emission quadrants. The reduction efficiency of pollutants emission was calculated and was equilibrated to economic growth. The primary industry was the main source of TN/TP load in Poyang Lake Watershed, emitting 6.43x10(4) ton and 1.14x10(4) ton, respectively, among which animal husbandry and fishery sector were the major contributors, contributing 77.3% (TN) and 73.4% (TP), and 13.7% (TN) and 20.3% (TP) of total emission. According to the influence coefficient and sensitivity coefficient, manufacturing, construction and the tertiary sectors played a dominant role in promoting economic growth in this area. Furthermore, mining, water-electricity-gas production and supply, construction sectors were highly sensitive to the economic growth. As long as emission reduction efficiency is concerned, TN/TP emission can be mitigated largely by decreasing the proportion of animal husbandry, fishery and manufacturing sectors in economic structure. This paper can provide valuable references for policy formulation to balance economic growth and environmental conservation in Poyang lake basin. |
