Space Division of Absorbing Livestock Manure Areas Based on Phosphorus Nutrient Demand of Crops in Farmlands
摘要
[目的
]
根据区域农用地作物养分需求
从区域空间集聚现象对北京市大兴区进行规模畜禽养殖废弃物消纳区域划分研究
以期为畜禽养殖废弃物的处理和环境污染防治、畜禽养殖场空间布局研究等提供依据。[方法
]
基于遥感影像获取农用地空间分布特征
利用空间关联指数法进行农用地作物磷养分需求空间聚类分析
并利用GIS空间分析技术
基于养分平衡的角度进行计算分析。[结果
]
北京市大兴区农用地磷养分需求的空间分布在整体上具有显著的空间正相关性
整个大兴区农用地大部分属于畜禽养殖废弃物消纳一般区域
高区域主要集中在瀛海镇、西红门镇、庞各庄镇和魏善庄镇
低区域主要集中在采育镇和北藏村镇。大兴区8481个农用地地块被划分成83个区域
其中区域中可消纳畜禽养殖废弃物磷养分平均量、最大量和最小量分别为1.10×10
5
kg
9.75×10
5

提供了一种较快速的划分畜禽养殖废弃物消纳区域、计算区域畜禽养殖废弃物消纳量及结果可视化表达的方法。
Abstract
[Objective] This paper tries to analyze the spatial division of absorbing capacity areas of livestock manure based on the nutrient demand of crops in Daxing district of Bejing City in order to provide supports for the treatment of livestock manure
the control of regional livestock feeding and spatial layout of livestock and poultry breeding.[Methods] The remote sensing technology was used to extract the spatial information of farmland
the space association index was used to analyze the spatial clustering of phosphorus nutrient demand of crops
and GIS spatial analysis technology was used to calculate and analyze the nutrient balance.[Results] In Daxing District of Bejing City
the spatial distribution of phosphorus demands of crops had significant spatial positive correlation on the whole. The most of farmlands belonged to the average level of absorbing capacity of livestock manure. The areas of high absorbing capacity of livestock manure mainly concentrated in towns of Yinghai
Xihong-men
Penggezhuang
and Weishanzhuang. The regions of low absorbing capacity of livestock manure mainly concentrated in towns of Caiyu and Beizangcun. The total of 8481 farmlands was divided into 83 regions
of which the average
maximum and minimum absorbing phosphorus nutrient of livestock manure is 1.10×106 kg
9.75×105 kg and 2.38×103 kg respectively. The maximum and minimum absorbing phosphorus nutrient of livestock manure is 13.54×106 kg in Penggezhuang town and 9.54×105 kg in Yizhuang town.[Conclusion] This paper provides a method to quickly divide absorbing capacity areas of livestock manure and to calculate absorbing amount of livestock manure and visual expression.
