一、

旅游资源开发对环境的影响是一个复杂的问题，涉及生态、社会、经济等多个方面。为了确保旅游资源开发的可持续性，对其进行环境影响评估至关重要。COBOL（Common Business-Oriented Language）作为一种历史悠久、稳定性强的编程语言，在数据处理和商业应用方面具有显著优势。本文将探讨COBOL语言在旅游资源开发系统环境影响评估中的应用，并通过实际代码实现，展示其应用价值。

二、COBOL语言的特点及优势

1. 稳定性：COBOL语言自1959年诞生以来，经过多次升级和改进，具有极高的稳定性，适用于长期运行的环境。

2. 易于维护：COBOL语言具有清晰的语法和结构，便于理解和维护。

3. 数据处理能力强：COBOL语言在数据处理方面具有丰富的库函数和操作符，能够高效处理大量数据。

4. 跨平台性：COBOL语言具有良好的跨平台性，可以在多种操作系统上运行。

三、旅游资源开发系统环境影响评估模型

1. 模型概述

旅游资源开发系统环境影响评估模型主要包括以下模块：

（1）数据采集模块：负责收集旅游资源开发过程中的各类数据，如生态环境、社会影响、经济效益等。

（2）数据处理模块：对采集到的数据进行清洗、转换和整合，为后续分析提供准确的数据基础。

（3）分析评估模块：根据评估指标和方法，对旅游资源开发的环境影响进行定量和定性分析。

（4）结果展示模块：将评估结果以图表、报告等形式展示给用户。

2. COBOL语言实现

以下为COBOL语言在旅游资源开发系统环境影响评估中的应用示例：
