摘要:
祁连山是我国西部重要的生态安全屏障,是国家生态安全核心区和重点治理区。为研究祁连山国家级自然保护区生态安全状况,本文基于该自然保护区的生态系统结构和功能特征,选取24项评价指标,构建PSR(压力-状态-响应)模型,以Delphi经典法确定权重,综合评价2008年、2016年祁连山国家级自然保护区的生态安全状况。结果表明:2008年不安全度为0.1934,处于稍不安全状态; 2016年为0.2454,较2008年增加了26.9%,处于很不安全状态。其中,压力因子的不安全度由0.1094升至0.1276,增加了16.6%; 状态因子由0.0593升至0.0748,增加了26.1%; 响应因子由0.0247升至0.0430,增加了74%; 说明响应层面不安全度上升最显著。2008年与2016年相比,人类活动增加及资源过度开发是祁连山保护区生态安全水平下降的主要原因,具体表现在旅游客流量大幅度持续增加、水电和矿产的不合理开发。本研究成果可应用于其他复杂生态系统的安全评价,为国家级自然保护区生态安全提供科学管理和决策依据。
Abstract:
To study the ecological security of Qilian Mountain National Nature Reserve(QMNNR),24 assessment indexes were selected and endowed with weights by classical Delphi method according to the structure and function of ecosystem of QMNNR in Gansu Province. Afterward, PSR(Pressure-State-Response)model was constructed to comprehensively evaluate the ecosystem security levels of QMNNR in 2008 and 2016, respectively. This study focused on exploring the research approach of the dynamic changes of ecological security and providing scientific basis for the improvement of ecological security situation in QMNNR. The results showed that QMNNR was at 0.1934 insecure degree in 2008 which demonstrated a bit of insecure level state, however, at 0.2454 insecure degree in 2016 which indicated a quite unsafe level state. Compare to 2008, the ecosystem insecure degree of QMNNR increased by 26.9% in 2016, i.e. one grade decrease of security level. The insecure degree of pressure factor increased from 0.1094 to 0.1276(16.6%); while, insecure status factor from 0.0593 to 0.0748(26.1%), and the response factor from 0.0247 to 0.043(74%). It suggests that the intensified human activities along with the excessive exploitation of resources were the main causes for the declining of the ecological security level of the QMNNR in 2016, especially the extreme continuous increasing number of tourists or visitors, over-exploited of hydropower stations and mines. To sum up, reasonable and efficient measures that closely related to its local conditions are urgently needed for the protection and restoration of QMNNR. This study has provided scientific management ways, as well as decision-making basis for the ecological security of national nature reserves.
