Abstract:

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 Lashihai 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.
