西青区生态质量气象评价及其动态变化分析

生态环境的优劣关乎到全人类的生存,当前经济发展对生态环境的破坏严重影响了社会的可持续发展。本文着眼于天津市西青区的生态质量,参考《生态质量气象评价规范（试行）》标准,利用卫星遥感数据,结合优势性地面观测气象数据,采用遥感图像处理、统计分析、目视解译、实地检验等方法,对西青区生态质量的气象评价方法进行了研究。通过遥感数据和气象数据,计算K（湿润指数）、NDVI（植被覆盖指数）、水体密度指数、土地退化指数、DIS（灾害指数）等参数,构建了西青区生态质量气象评价指数模型,对西青区生态环境现状和变化进行气象评价与分析,为西青区生态监测的全面开展和生态评估系统的建立提供了一定的技术方法和理论参考。

Meteorological Evaluation and Dynamic Change Analysis of Ecological Quality in Xiqing District

This project aims at the existing problems in the meteorological operation of ecological quality meteorological evaluation in Xiqing District, referring to the standard of "Ecological Quality Meteorological Evaluation Standard (Trial Implementation)", uses remote sensing data as the main part, and uses meteorological ground observation, statistics, on-the-spot investigation and other data to carry out the research on the meteorological evaluation method of ecological quality in Xiqing District. The meteorological evaluation index model of ecological quality is established by selecting five indexes, namely, wetness index, vegetation cover index, water body density index, land degradation index and disaster index, to carry out meteorological evaluation and analysis on the current situation and changes of ecological environment in Xiqing District, so as to provide certain technical methods and theoretical references for the comprehensive development of ecological monitoring and the establishment of ecological evaluation system in Xiqing District.
