大尺度景观保护已成为生物多样性保护中的重要举
措,但其保护成效究竟如何,还未得到充分验证,中国国家
公园建设为验证其成效提供了良好契机。以神农架国家公园
体制试点为案例,以景观破碎化综合指数为评估指标,采用
倾向得分匹配法建构反事实评估模型以克服样本选择的内生
性偏差,评价国家公园体制试点的生态成效。分别比较了神
农架国家公园体制试点内非自然保护区、神农架国家公园体
制试点内原国家级自然保护区与其各自的对照区在试点建立
前后的景观格局变化情况。结果表明,神农架国家公园体制
试点在减缓景观破碎化、提升生态保护成效方面发挥了积极
作用,尤其是在对非原有保护区的保护上取得了显著成效。
然而,对于原有国家级自然保护区,体制试点的进一步保护
措施效果提升并不明显,需要更长时间观察或更深入的干预
措施才能显现出其保护效果。 |

Ecological Effectiveness Evaluation of LandscapeConservation: A Case Study of the ShennongjiaNational Park System Pilot |

Abstract: |
Large-scale landscape conservation has become
an important measure in the protection of biodiversity, but its
effectiveness has not been fully verified. The construction of
national parks in China provides a good opportunity to verify their
effectiveness. Taking the Shennongjia National Park system pilot as
a case study and using the comprehensive landscape fragmentation
index as an evaluation indicator, this study adopts the propensity
score matching method to construct a counterfactual evaluation
model to overcome the endogeneity bias in sample selection and
to evaluate the ecological effectiveness of the national park pilot
system. This research compares the changes in landscape patterns
before and after the establishment of the pilot in the non-nature
reserve areas within the Shennongjia National Park system pilot, the
original national-level nature reserve areas within the Shennongjia
National Park system pilot, and their control areas. The study
found that the Shennongjia National Park system pilot has played a
positive role in mitigating landscape fragmentation and enhancing
ecological protection effectiveness, especially in the protection of
non-original protected areas where significant results have been
achieved. However, for the original national-level nature reserves,
the further protective measures of the pilot system did not show a
significant improvement in effectiveness, and a longer period of
observation or more in-depth intervention measures are needed to
demonstrate their protective effects. |
