AbstractNational Forests Forests Forest tengrang forest bayetphan and strip in the study of plant diversity. We divided the study area into two as forest plantations and natural forests. A study on the biomass and cover the plants green, national forests of the forest strip using a geographic information system will provide a variety of plants with collected data by placing a temporary exploration 20 m x 20 m number 27 using the principle of putting random transformations and the proportion of cover crops, Green has made a study of satellite images Landsat 8 by using the derived analysis.From the study (the forest planting). There are a large number of found wood wooden young Antelope number 55 type 24 42 21 types of wooden flooring and the lower number of 52 House type House with 34 stalls of the kind of big wood (H) Wood, wooden floor and young bottom is equal to 3.15 3.19 and 3.21, respectively. Plant type index with the value of plants is a Rails to wooden parts with 19.94 young index, the most important is the tightening of the vampire gold equal to the lower part of wooden flooring, 29.39 found orange is 63 and wind up a portion of the green plant cover of the area studied is the average equivalent to 65.06.From the study of (wild) There are a large number of found wood wooden young Antelope number 41 24 type 30 kinds of wooden floors and the lower number of the 19 's 48 28 House type with a range of softer types (H) of the big wood. Wood, wooden floor and young bottom is equal to 2.68 2.68 and 2.55, respectively. Plant type index with the value of the plants, the most important tattoo to 69.43 best young wood at the most important indices is equal to 66.72 Mok best wood floor below the most common is the grass and up the PEK 270 portion of the green plant cover of the area studied is the average equivalent to 41.43.From the quantity of biomass Forest plantations can recognize the weight of each section are as follows: Dry weight kg dry weight, stem = 3,281,402.577 = twigs and dry weight, the 1,072,684.546 kg = 15355.67666 kg, and the total biomass values = 699.1108479 tonnes 4369.442799 tonnes/Hague/Rai or tae.From the quantity of biomass Natural forest can recognize the weight of each section are as follows: Dry weight kg dry weight, stem = 1,496,291.451 = twigs and dry weight, the 440,160.8485 kg = 12472.81497 kg, and the total biomass values = 311.8280183 tonnes 1948.925114 tonnes/Hague/Rai or tae.Key words: colorful, sensual, kind of an index of plants, the proportion of cover crops, green,Biomass
