- 摘要:
- 土地利用生态效益的优劣是人民日常生活和国民经济健康、良性和持续发展的根本保证。从生态条件、生态平衡性、环境质量、环境治理能力等方面，构建土地利用生态效益评价指标体系，采用综合评价法、AHP法、熵权法对黑龙江省2000—2011年的土地利用生态效益及其协调度进行了评价。结果表明：黑龙江省土地利用生态效益值总体呈波动性上升，其中2006年和2008年出现2次波动；哈尔滨市、鹤岗市、佳木斯市、伊春市和绥化市在研究期内土地利用生态效益值增长最快，2011年其土地利用生态效益值均达到了0.75以上；土地利用生态效益协调性状态先升后降，尤其2004—2006年全省及城市的协调性皆比较高，且研究期末的协调状态好于研究初期；最后，针对研究结果，提出了加强土地利用生态环境建设的对策建议。
- Abstract:
- The quality of land use ecological efficiency is fundamental guarantee of people’s daily life and healthy sustainable and benign development of national economy. This paper established evaluation indicators for land use ecological efficiency from the aspects of ecological conditions, ecological balance, environmental quality and the ability to control environment. The method of AHP and entropy was used, the weights of each indicator was calculated. A case study in Heilongjiang Province was carried out to analyze the land use efficiency and its evolvement by using the methods of multifactor composite evaluation from 2000 to 2011. Result indicated that the overall level of land use eco-efficiency values rose in volatility, there were fluctuations in 2006 and 2008; the land use eco-efficiency values of Harbin City, Hegang City, Jiamusi City, Yichun City and Suihua City in the study period were the fastest growing, In 2011, the land use eco-efficiency value was above 0.75, the coordination state of eco-efficiency for the period first increased and then decreased, especially the coordination level from 2004 to 2006 of Heilongjiang Province and cities was higher, and the end was higher than the first. Finally, based on the research results, countermeasures and suggestions were put forward for enhancing the construction of ecological environment.
