从地区产业结构变动、产业结构阶段性判别、产业结构的生态环境效应等方面,分析四川省宝兴县产业结构变动对生态环境的影响。结果表明:近三十年来,宝兴县产业结构由1978年的“一、二、三”型转换成2007年的“二、一、三”型;按照Chenery“标准模式”评价,宝兴县经济水平已达到工业化中期阶段,但产业结构仍停留在工业化初期阶段,产业结构转换滞后于经济发展;产业结构逐渐形成以畜牧业、石材加工业、建筑业为主导的经济发展模式;产业结构的生态环境影响由1990年的“中等”发展到2007年的“较重”水平,不同产业的生态环境效应表现出差异,农业、林业、轻工业的生态环境影响效应逐年降低,重工业、畜牧业和建筑业对生态环境的影响呈加重趋势。
This paper analyzes the impact of industrial structure change in Baoxing County of Sichuan Province on the ecological environment from the aspects of the regional industrial structure change, the stage identification of industrial structure and the eco-environmental effect of industrial structure. The results show that the industrial structure of Baoxing County has been transformed from “one, two and three” in 1978 to “two, one and three” in 2007 according to Chenery “standard model ”Evaluation, Baoxing County, the economic level has reached the mid-stage of industrialization, but the industrial structure is still in the early stages of industrialization, the transformation of industrial structure lags behind economic development; industrial structure gradually formed to livestock husbandry, stone processing industry, construction-led economy Development mode; the ecological and environmental impact of industrial structure has been expanded from “medium” in 1990 to “heavier” in 2007, and the ecological and environmental effects of different industries show differences. The ecological and environmental impacts of agriculture, forestry and light industry The effect is decreasing year by year, and the impact of heavy industry, livestock husbandry and construction industry on the ecological environment is on the rise.
