Abstract

Abstract: The method,processing technique were described and four models and some results were developed and presented for dry matter(DM) estimation of four major grassland types in Tibet using ground-level remotely-sensed data of Agriculture Digital Camera(ADC).There was a high regressive relationship between NDVI and sampling data.Combination of NDVI and ADC showed additional advantages in DM availability measurement in comparison to conventional electronic devices,and it would be a useful method for monitoring small scaled grasslands and animal production systems analysis.

Key words: Agriculture digital camera, Biomass, Tibetan grasslands, Dry matter, Availability

摘要： 应用农业数字化照相机(ADC)测定西藏草地干物质(DM)量,并与野外采样测定数据相结合,用植被指数测定草地DM量的估测模型。本次研究为4个主要草地类型(高寒草原、高寒草甸、以西藏嵩草为建群种的高寒草甸以及针茅属草为优势种的高寒草原)建立了DM估测模型(与实际有较好的拟合度)。该方法为小尺度的草地研究、动态监测和畜牧业生产提供方便、实用、经济且较准确的方法和技术。
