山核桃环境指数分析数据

根据当地环境保护局发布的环境状况公报，收集历年水、土壤、大气各个环境指标数据，采用极值法消除各个指标的量纲，然后采用均值权重法等计算山核桃环境分析指数，用于向消费者反馈产地自然环境，有利于向消费者传递原产地环保特色，向消费者传递当地山核桃的健康理念，有利于当地山山核桃产品的市场销售和品牌传播。1数据来源
根据当地环境保护局发布的环境状况公报，收集历年水、土壤、大气各个环境指标数据，地表水环境质量水质达到Ⅲ标准比率、地表水环境质量水质达标率、工业企业废水排放量、化学需氧量排放、河道水质达标率、二氧化硫年日均值、PM10年日均值、空气质量优良天数、空气质量优良率、PH值年均值、酸雨率、工业企业废气排放量、二氧化硫排放量、烟尘排放量、土壤PH值、氮含量、磷含量、钾含量等涉及水环境、大气环境、土壤环境的18个关键因子。
2.数据处理
2.1采用极值法消除各个指标的量纲，即找到历年数据中最大或最小的值。
2.2由于不同因素的量纲不同，需要对数据进行归一化处理，公式为X'=X/Xmax或Xmin/X。
2.3 归一化后的各个指标数求和得到环境得分，环境指数由当期得分和基准得分相比后乘以100。
3.数据应用
计算山核桃的环境指数，向消费者反馈产地的自然环境，有利于向消费者传递山核桃原产地环保特色，向消费者传递山核桃的健康理念，有利于山核桃产品的市场销售和品牌传播。同时环境指数用于计算山核桃综合指数。

Based on the Environmental Status Bulletin released by the local Environmental Protection Bureau, historical environmental index data of water, soil and atmosphere are collected. The extremum method is adopted to eliminate the dimensions of each index, and then methods such as the mean weight method are used to calculate the environmental analysis index of Chinese hickory. This index is used to inform consumers of the natural environment of the producing area, convey the environmental protection features of the origin and the health concept of Chinese hickory, and facilitate the market sales and brand communication of local Chinese hickory products.

1. Data Source
The historical environmental index data covering water, atmospheric and soil environments are collected from the Environmental Status Bulletin released by the local Environmental Protection Bureau, including 18 key factors: the ratio of surface water environment quality reaching Grade Ⅲ standard, surface water quality compliance rate, wastewater discharge volume of industrial enterprises, chemical oxygen demand (COD) discharge, river water quality compliance rate, annual daily average concentration of sulfur dioxide, annual daily average concentration of PM10, number of days with excellent and good air quality, proportion of days with excellent and good air quality, annual average pH value, acid rain rate, waste gas discharge volume of industrial enterprises, sulfur dioxide emission, soot and dust emission, soil pH value, nitrogen content, phosphorus content and potassium content.

2. Data Processing
2.1 The extremum method is used to eliminate the dimension of each index, that is, to find the maximum or minimum values in the historical data.
2.2 Since different factors have different dimensions, normalization processing is required, with the formula: X' = X / X_max or X' = X_min / X.
2.3 The environmental score is obtained by summing the normalized index values. The environmental index is calculated by dividing the current period score by the baseline score and then multiplying by 100.

3. Data Application
Calculate the environmental index of Chinese hickory to inform consumers of the natural environment of the producing area, which helps to convey the environmental protection features of the origin and the health concept of Chinese hickory to consumers, and is conducive to the market sales and brand communication of Chinese hickory products. Meanwhile, the environmental index is used to calculate the comprehensive index of Chinese hickory.
