农村居民点整理的产能潜力测算

Estimation of Land Productivity Potential of Rural Residential Consolidation

农村居民点的自然本底特征与相邻耕地的立地条件具有较强的相似自然属性。通过计算居民点整理自然质量分与标准自然质量分的差值,对河北省临西县居民点整理后的土地适宜性进行了评价。研究得出,临西县居民点整理后的新增耕地为474.63hm2,新增园地数量为367.28hm2,新增林地数量为0.24hm2。确定了可以被整理为耕地的居民点,然后在ArcGIS 10.0中将邻近耕地的国家自然质量等别位置赋属性给居民点,确定整理后耕地的等别,计算出临西县居民点整理后的产能潜力为6 783.45t。最后,利用聚类分析法对临西县居民点整理后的耕地进行了分区。一级整理区可新增产能3 282.52t,二级整理区可新增产能1 964.80t,三级整理区可新增产能1 536.13t。

The natural background characteristics of the rural residential areas and their site conditions of adjacent land have stronger similarity nature attribute. Based on calculating the difference between the natural quality score of the residential land reclamation and the standard nature quality score, the land suitability was evaluated after the ru- ral residential land was consolidated. The results showed that after the rural residential land was consolidat- ed, it can increase 474.63 hm2 arable land, 367.28 hm2 garden land and 0.24 hm2 woodland. The residential land which can be consolidated as arable land was identified, and then the land level will be determined after rural residential land was consolidated using the function ＂join data from another layer based on spatial location＂ in ArcGIS 10.0, and the rural residential land consolidation potential production capacity of all the county was calculated to be 6 783.45 t. At last, using the cluster analysis method, the rural residential land in Linxi County after the consolidation had be divided into different areas, it showed that the increasing production capacity of the class I area can reach 3 282.52 t, the class Ⅱ area can reach 1 964.80 t, and the class Ⅲ area can reach 1 536.13 t.
