Problems solved by technology

However, the above-mentioned evaluation criteria do not involve the composition and spatial pattern of the landscape of terrestrial nature reserves, and the above-mentioned evaluation method adopts the method of expert consultation and scoring, which largely relies on the subjective judgment of experts and lacks objectivity
At present, there is no way to quantitatively and objectively measure the landscape protection value of a terrestrial nature reserve

Embodiment Construction

[0071] Taking the forest ecosystem type nature reserve Jilin Changbai Mountain National Nature Reserve as an example, the invention provides a method for assessing the landscape protection value of the nature reserve, said method comprising the following steps:

[0072] (1) Step 1: ①Based on the landscape classification system of nature reserves (Table 1), combined with the landscape characteristics of Changbai Mountain National Nature Reserve, determine the specific landscape types of Changbai Mountain National Nature Reserve: 0111 natural forest, 0112 artificial forest, 0121 Natural sparse forest land, 0131 Natural shrub forest, 0142 Artificial afforestation, 0211 Natural grassland, 0331 Permanent freshwater lake, 0511 Bare land, 0531 Bare rock and gravel land, 0631 Dry land, 0711 Orchard, 0811 Commercial land, 0823 Storage land , 0842 land for scenic spots, 0843 land for public facilities, 0844 other public land, 0853 other special land, 0862 road land, 0863 forest road, 087...

Abstract

The invention discloses a method for calculating landscape protection value of land nature reserves. By the method, the landscape protection value of the land nature reserves can be objectively quantized, landscape protection value indexes of the land nature reserves are given, the landscape protection value of the nature reserves in the same type can be sorted, and the comparability of the landscape protection value of the nature reserves is enhanced.

Description

technical field [0001] The invention relates to the field of nature protection, in particular to a method for calculating the landscape protection value of terrestrial nature reserves of forest ecosystems, grassland and meadow ecosystems, and desert ecosystems. Background technique [0002] The conservation value of nature reserves can be used not only as a criterion for establishing nature reserves, but also as a basis for judging whether nature reserves should be prioritized. At present, the evaluation of the protection value of my country's nature reserves is based on the "National Nature Reserve Evaluation Standards" issued by the Ministry of Environmental Protection. The review index consists of three parts: natural attributes, protectable attributes and protection management basis. The natural attributes of terrestrial nature reserves involve five indicators: typicality, vulnerability, diversity, rarity, and naturalness. The two indicators of protectable attributes an...
