The Study On Spatial Distribution Of Cultivated Land Classification In Taoyuan County

The study through the investigation of the natural condition and social economy condition of Taoyuan County, Using the latest achievements of the second land use survey of Taoyuan County, to add updates the land grades. By using the spatial analysis of Mapgis6.7and Excel tools for natural quality land grades, land use grades and land economy grades, The quality of cultivated land in Taoyuan county and related conclusions different spatial distribution.The main findings and conclusions were as follows:(1) From the number of distribution, the total of96,294.92hectares of arable land county, where higher ground (1-5)49,469.55hectares, accounting for51.37%; moderate manner (6-10)42,498.54hectares, accounting for44.14%; low grades (11-15)4326.83hectares, accounting for4.49%, moderate to higher ground, and accounted for95.51%, indicating a better overall quality of cultivated land in Taoyuan County.(2) From the distribution of three level indicators region, along the River in Binhu plain region (northeast region) of cultivated land quality mean grade (2.9) was obviously better than that of the Low Hill Gang District (county,west southwest) average classification (5.9).(3) From the altitude of less than400meters above sea level, the area of cultivated land quality mean grade3.6, at an elevation of400meters to700mete-rs between the regional cultivated land quality mean grade6.3, elevation700mete-rs to800meters between the regional cultivated land quality mean grade is8.5, the area was clear of the growth trend, cultivated land grade also preferentiall degradation.(4) From the point of view of loam and clay soil texture, high proportio-n of theregion such as the Qihe Town, Tao Huayuan Town, land of otherhigh proportion of higher. The sandy and gravelly soil is not suitable for the gro-wth of crops, such as Mu Tangyuan Town, Longtan Town, in different proporti-on.(5) From the level of economic development situation, Taoyuan county land average grades is4.4, The quality of cultivated land is better. High level of economic development of the region, The quality of cultivated land is better.
