The project of Tengchong, land resource evaluation, was supported by software-ARC/INFO. After ITUM was digitized, it was used as base for land resource evaluation in Tengchong.Two models for evaluation, TT = VI* (V2 + V3 + V4)/3* 0.01 and TT2 = V1*V2*V3*V4* 0.000001, were designed.

Integrated Terrain Unit Map (ITUM) with several overlays of land elements is being developed in the world. The ITUM is a new computer mapping system. The project of Tengchong, land resource evaluation, was supported by software-ARC/INFO. After ITUM was digitized, it was used as base for land resource evaluation in Tengchong.Two models for evaluation, TT = VI* (V2 + V3 + V4)/3* 0.01 and TT2 = V1*V2*V3*V4* 0.000001, were designed. It was borne out that the first model was better than the second one by comparing output maps of evaluation with land-use map of Tengchong.By use of statistic analysis for data, four classes of land were divided:Class 1, Lands in class 1 have few limitations that restrict their use.Class 2, Lands in class 2 have some limitations that reduce the choice of plants or requiremoderate conservation practices.Class 3, Lands in class 3 have severe limitations that reduce the choice of plants or require special conservation practices.Class 4, Lands in class 4 have severe limitations that make them generally unsuited to cultivate.Area of 541.91 sq. km is suitable to farm in Tengchong. It is onely 29.52 per cent of whole area. But now, area of 534.94 sq. km has been cultivated and a few arable virgin in Tengchong can be cultivated.

具有几个土地要素层的综合土地单元制图在土地研究中正在获得日益广泛的应用,它是计算机制图的基础。腾冲农业土地资源评价是在 ARC/INFO 软件系统支持下,在综合土地单元图的基础上进行的。 本研究通过对比,应用了评价模式 TT=V1*(V2+V3+V4)/3*0.01,根据土地对农业利用的适宜程度,将腾冲地区的土地分为四个适宜性等级。

Land resources refer to the land that can be used by people both at presentand in future for the productions of agriculture, forestry and animal husbandryetc.,Which consists of two respects-the land quality and the land quantity.The assessment of land quality is the core of land rescurces evaluation.Theprinciple methods used in the current land resources evaluation are the ado-ption of the concepts of suitability and limit and the determination of evalua-tional indexes. The land quality degree is determined mainly by land natural property,thestudy of which and its productive effects are the main contents of the land-type science. Therefore, land types are the foundation for land resourcesevaluations which are in turn determined by the land-type classifications.There are four different classes divided in this paper to suit the followinglegend scopes: <1: 1000000 for the first-class land resources classificationsystem, 1: 200000~1: 1000000 for the second-class, 1: 50000~1: 100000for the third-class and<1: 50000 for the fourth-class.
