With the continuous development of the oblique photography technique, it has been used more and more widely in the field of geological disasters. It can quickly obtain the three-dimensional(3D) real scene model of dangerous mountainous areas under the premise of ensuring the safety of personnel while restoring the real geographic information as much as possible. However, geological disaster areas are often accompanied by many adverse factors such as cliffs and dense vegetation. Based on this, the paper introduced the flight line design of oblique photogrammetry, analyzed the multi-platform data fusion processing, studied the multi-period data dynamic evaluation technology and proposed the application methods of data acquisition, early warning, disaster assessment and decision management suitable for geological disaster identification through the analysis of actual cases, which will help geologists to plan and control geological work more scientifically and rationally, improve work efficiency and reduce the potential personnel safety hazards in the process of geological survey, to offer technical support to the application of oblique photogrammetry in geological disaster identification and decision making and provide the scientific basis for personal and property safety protection and later-stage geological disaster management in disaster areas.

Economic globalization is the core of information technology, information technology is the core of e-commerce. E-commerce is as an important part of inlbrnaation technology in recent years when China has been booming. For a large number of SMEs, human resources, capital, technology and information are in a relatively weak position, in addition, in recent years, changes in the external environment in which small and medium enterprises are also reflected in： international trade friction increase, RMB such as the increasing appreciation of the exchange rate increase, it raises the cost of export products. Under the new situation, how to find space for development, how to implement e-commerce strategy, clutches the huge growth opportunities given the times, to keep pace with the times, in an invincible position in the competitive market environment, many small and medium enterprises become China＇ s urgent problems.

当前，人类社会对生态系统服务的需求和消费日益增加，由此引发了生态系统服务的变化。然而，生态系统服务的消费机制仍然是一个空白的研究领域。本文以生态系统服务—消费—管理的互动关系为主线，从理论基础和实践应用的角度，对生态系统服务消费的概念理论、基本范式、度量体系和管理框架进行了探讨，将与人类消费关系密切的生态系统的供给功能分为生产功能和承载功能，将生态系统服务消费定义为人类生产和生活对生态系统服务的消耗、利用和占用，生态服务消费区分成直接消费和间接消费两种基本模式，强调生态系统服务直接与间接产品界定和消费者确定在生态系统服务消费研究中的重要性，初步给出了两种生态服务消费的不同计量方法。研究提出生态系统服务消费的函数表达式为：Ec＝Edc［f（Xa，Xhz，Xgen，Xedu，Xbev，Xcmr，Xinc，…，Xn）］＋Eidc。生态系统服务消费研究将为政府在生态系统服务的投资、贸易、补贴、税收等方面的决策，提供科学依据。

关键词：生态系统服务消费模式度量方法决策管理 Consumption of ecosystem services Models Measurement decision management
