The specific aspects are as follows:

1. In the agricultural ecosystem, it is necessary to maintain the balance of the number and distribution of various biological populations and avoid the over-reproduction of certain species or the overproduction of certain species. Too few species lead to imbalance in the ecosystem.

2. The diversity of biological species, including plants, animals and microorganisms, needs to be maintained in agricultural ecosystems. This helps to enhance the stability and stress resistance of the ecosystem and reduce the occurrence of pests and diseases.

3. Agricultural ecosystems not only need to provide agricultural products, but also need to provide ecological services, such as purifying the air, preserving soil and water, and providing habitats. These factors need to be considered when building an agricultural ecosystem.

4. Use modern scientific and technological means, such as the Internet of Things, big data, artificial intelligence, etc., to achieve intelligent management of agricultural ecosystems and improve production efficiency and resource utilization.
