摘要:

开展草原鼠害防控工作有利于降低草原鼠类密度,从而达到鼠类存在而不致灾的目的。对维护国家生态安全和国土安全、牧区经济及社会可持续发展等具有重要意义。本研究以全国现有草原鼠害防控实际情况为基准,结合草原鼠害防治质量发展方向,构建了草原鼠害防控质量评价指标体系,并采用熵权TOPSIS模型进行分析,科学评价了2019-2021年全国草原鼠害防控质量。研究结果表明,在防控质量评价中,防治投入权重占比最大,其次是防治成效投入,最后是组织建设。2019-2021年间全国草原鼠害综合评价、组织建设、防治投入和防治成效评价整体偏低,均为一般或较差水平,同时草原小省在综合评价、组织建设、防治成效方面显著优于草原大省。本研究可为调整草原鼠害防控过程中各组分的重新分配提供依据。

Abstract:

Grassland is a complex socio-economic ecological composite system and a valuable resource providing many ecosystem services. However, due to climate change and excessive human usage, grassland has become more and more vulnerable to ecological instability in recent years. One problem needing to be addressed is the control of rodent populations in grassland. Poisoning of rodents has also reduced the populations of natural predators, both by effects of the poison directly, and depriving natural predators of food indirectly. The result has often been a serious rebound of rodent populations after initial control by poisoning, therefore, emphasis is now moving towards ‘green’ control of rats allowing them to exist in the ecosystem without population explosion events. It is urgent to develop new models to refine and evolve this new approach to rodent control. In response to that need, we developed an objective TOPSIS (technique for order preference by similarity to an ideal solution) model to examine the status of rodent control across 14 provinces, accounting for 99% of grassland area of China. Of the 14 provinces, six were classified as major grassland provinces with 95% of China’s grassland between them, and the other eight as minor grassland provinces. The results showed that rodent eradication program evaluation scores were highest for investment in prevention and control, followed by scores for outcomes, with scores for infrastructure and organizational development the lowest. From 2019 to 2021, the overall score across the three areas evaluated was generally low, rating as is average or poor. Interestingly, minor grassland provinces performed significantly better than major grassland provinces in the overall evaluation. This study provides objective data for adjusting resource allocation for improved outcomes in the process of grassland rodent management and prevention of harmful population explosion events.
