摘要
随着我国经济形势的发展和变化,残次林地后备资源开发已成为缓解占补平衡压力,保障耕地资源和粮食安全的一项有效途径。由于依靠传统的作业方式已难以快速、准确地调查残次林地资源,因此,如何实现对残次林地范围的有效判别和界定是当前必须要面临的一项重要问题。本文以渭北台塬区千阳县项目为研究对象,以遥感影像资料为基础,以内业数据处理和外业踏勘调查相结合的方式,对残次林地资源遥感解译的判别和技术应用进行分析研究,形成了全面系统的残次林地有效判别和界定方法,以期为台塬区残次林地土地整治项目的实施提供技术支撑和实践经验。
With the development and changes of China’s economic situation,the development of reserve forest resources has become an effective way to ease the pressure of occupation and compensation,and to ensure the resources of cultivated land and food security.Because it is difficult to quickly and accurately investigate the detective forest land resources by relying on traditional methods of operation,how to effectively identify and define the scope of the detective forest land is an important issue that must be faced at present.This paper takes the Qianyang County project as the research object,and based on the remote sensing image data,combines the internal data processing and the field survey to analyze the discrimination and technical application of remote sensing interpretation of detective forest resources.The research has formed a comprehensive and systematic method for effective identification and definition of detective forest land,with a view to providing technical support and practical experience for the implementation of the land remediation project for the defective forest land in Loess Platform region.
