摘要
提出了自然保护区保护成效评估模型,该模型由6项评估指标、17项次级指标量化计算。利用两期的Landsat的TM的多光谱波段数据及基础地理数据为数据源,解译和分析了2010年和2016年拉市海自然保护区的变化情况,计算各指标在评估期内的变化程度,对拉市海保护区的保护成效进行评价,评估结果表明拉市海高原湿地省级自然保护区保护成效一般。其主要原因是:2010—2016年,景观镶嵌体破碎化程度有所降低,景观保护有效性较好,水体面积有所增加,保护物种及种群数量保持稳定;但是,湖滨带面积减少,流域面山植被盖度及面积减少,保护区内建设用地增加和人为干扰增强。最后针对保护区现存的问题,提出了提高保护成效的办法。
This paper presents a model to evaluate the conservation effectiveness of Lashihai Nature Reserves. The model( used in this paper) is calculated from six evaluation indexes and seventeen sub-indexes. Based on the basic geographic data and multi-spectral band data of Landsat TM' s two phases,this paper interprets and analyzes the changing situations of Lashihai Nature Reserve in 2010 and 2016. In addition,the change degree of each index in the evaluation period was calculated and the protective effects of Lashihai Nature Reserve was estimated. The evaluation results show that the protective effects in Lashi-hai Plateau Wetland Provincial Nature Reserve is unsatisfied. The main reasons are as follows: although the degree of fragmentation of the landscape mosaic was reduced during the period from 2010 to 2016,the landscape protection seems to be effective and water area has increased,the number of protected species and populations remain unchanged,but the construction land is increased and the man-made disturbance is enhanced,and the vegetation coverage and area of the watershed are reduced. Finally,based on the existing problems,this paper proposed a solution to improve the effectiveness of protection.
