广西壮族自治区草原综合植被盖度监测研究

通过草原综合植被盖度监测，主要调查草原样地基本特征、地理位置（经纬度）、主要植物种类、样地综合植被盖度等要素，综合测算广西草原综合植被盖度。结果表明，本次调查广西共布设监测样地812个，测算出草原综合植被盖度为82.76%，较2019年提高0.93%，其中，热性草丛类、热性灌草丛类、暖性灌草丛类植物的综合植被盖度分别为84.11%、82.88%、89.00%。同时对关系草原综合植被盖度变化原因及存在问题进行分析，提出相关建议，以期为广西全面建成小康社会统计监测指标体系和广西绿色发展指标体系提供重要基础指标数据。

Monitoring of Comprehensive Vegetation Coverage of Grassland in Guangxi

By monitoring the comprehensive vegetation coverage of grasslands, this paper mainly investigated the basic characteristics, geographical location (latitude and longitude), main plant species, and comprehensive vegetation coverage of grassland sample plots, and calculated the comprehensive vegetation coverage of grasslands in Guangxi. The results showed that a total of 812 monitoring plots were set up in Guangxi during this survey, and the comprehensive vegetation coverage of grasslands was 82.76%, an increase of 0.93% compared to 2019, among which, the comprehensive vegetation coverage of thermal grassland, thermal shrub grassland, and warm shrub grassland plants was 84.11%, 82.88%, and 89.00%, respectively. At the same time, this paper analyzed the change reasons and existing problems in comprehensive vegetation coverage of grasslands, and proposed relevant suggestions, in order to provide important basic indicator data for the comprehensive construction of a moderately prosperous society statistical monitoring indicator system and the green development indicator system in Guangxi.
