Forest soil is one of the most important components of a forest ecological system, and forest soil resources in China are rich and various, so that the forest soil has obvious horizontal and vertical zonal distribution patterns. The process for acquiring the forest soil data is complex, the cost is high, and the current situation that the forest soil data is multi-source and heterogeneous and difficult to manage and apply is caused.
The traditional forest attribute database generally does not contain soil attribute data, and the soil attribute database also does not contain forest attribute information, so that the forest attribute information and the soil attribute information exist as two independent bodies, and the existing work does not interconnect the two information, therefore,
1. when in storage, in order to enable information to be matched, two databases are required to store corresponding identification information, redundancy is increased, and meanwhile storage and maintenance cost is increased;
2. in maintenance, in order to update one piece of data, two databases may need to be operated simultaneously, so that data consistency is difficult to ensure, and particularly when a plurality of tasks are performed simultaneously, the difficulty is higher;
3. in use, to query a piece of data, it is necessary to span two databases and then merge the data, which is inefficient.
Based on the reasons, the invention designs a construction method of the multi-source forest soil attribute database, which is characterized in that the forest soil unit data standard is formulated after the historical observation data, the literature data and the sample plot investigation data are fully collected, integrated and utilized, and the multi-source forest soil attribute database is constructed, so that the forest soil attribute related data in various formats can be efficiently managed at the same time.

s1, verifying whether data accords with a specification by utilizing a rule defined by the data;
s2, detecting data to be put in storage by using historical observation data, if the data fall within a reasonable numerical range of the data, the data are regarded as effective data, otherwise, users are prompted that abnormal values possibly exist in the data;
the data operation comprises data addition, data deletion, data modification and data query, and in order to efficiently manage data, the database system uses a unified SQL language for inquiring, the SQL language supports data analysis and geographic information inquiry, and when the object of the data operation is file data, the operation is performed in a mode of only adding and deleting, so that history information can be conveniently recorded;
the data backup adopts a corresponding backup mode for data from different sources, and specifically comprises the following steps:
for the structured data, backtracking the data by adopting a backup log mode, and merging database data in the backup log, so that the database is convenient to recover;
and for the file data, backing up the newly added file.
