【摘要】 加强生态环境建设，促进生态、经济和社会协调发展，已成为人类的共识。近年来，随着遥感、地理信息系统等技术的飞速发展，景观生态学理论研究与应用中逐步采用现代高新技术，并将它们融入到景观生态分析、评价与规划的各个环节中。现代高新技术的应用，能够更好的为区域范围内的景观生态建设提供技术支持。 本论文以景观生态学的基本原理为依据，以信息系统技术为手段，设计并实现了昌平区景观生态分析及规划信息系统。其构建模式基于ESRI公司的MapOb iects组件和微软Visual C++软件开发环境。系统的功能模块包括输入输出、显示编辑、查询统计、数据集管理、景观指数库管理、景观分析与辅助规划等。该系统能够将区域内景观斑块的各种资料与信息进行贮存、管理、修正和显示，并运用各种定量化的指标进行景观格局描述与分析，从而进行综合的、多样的评价与景观辅助规划。 昌平区景观生态分析及规划信息系统采用灵活的景观指数管理模式。系统内置了景观丰度、斑块数目、面积、周长、景观比例、斑块密度、分维数、多样性指数、优势度指数、分离度指数、破碎度指数等常用的景观指数，并允许用户在此基础上扩展和自行建立相应的景观指数及各种景观评价模型。 论文以“昌平区2003年京津风沙源治理工程”为实例，对系统的正确性和实用性进行了验证。证明该系统可以作为昌平区生态建设规划的辅助工具，具有一定的实用价值。更多还原

【Abstract】 In recent years, the development and application of hi-techs are rapidly. Hi-techs such as remote sensing and geographic information system are introduced in landscape ecology researches and practices. GIS technologies are playing important role in landscape ecological analysis, evaluation, layout projects.Based on the theory of landscape ecology and GIS technology, this thesis designs and implements the CHANGPING Landscape Ecological Analysis & Layout Information System with ESRI MapObjects component and Microsoft Visual C++. This information system has following function modules: input/output, display, edit, query, statistic, landscape indexes management, landscape analysis, assistant planning modules. It is capable of assembling, storing, manipulating, displaying geographic-referenced information, such as landscape information or patch data, calculating various quantitative landscape indexes to analyze and describe landscape structure. It can provide assistant landscape analysis and planning for Changping district.The Changping Landscape Ecological Analysis & Layout Information System adopts an agile landscape index management model. Not only the information system is able to calculate some common landscape indexes, such as landscape number, patch number, area, perimeter, landscape scale, patch density, fractal dimension, diversity, dominance, isolation, fragmentation, but also base on them, can users create or expand their own-defined landscape indexes or evaluating models.The information system is instanced by the data of Changping district’s Harness Desertification in Beijing&Tianjing Districts Project to validate its correctness and practicability. As a result, it is established that the information system has its own validity and can be applied to eco-environment projects of Changping district.更多还原
