1.农业景观结构之间的关系，作为一个功能的耕地面积和发生的永久性覆盖，丰富的昆虫食物和parabelchick生存在波兰的两个地区进行了研究。一个地区有小块和大块田地（琴平），另一个地区只有小块田地（库特诺）。育雏大小被用来作为一个指数的小鸡生存和植物错误（异翅目）的数量作为一个指数的小鸡食物资源。2.在谷物中的植物错误的数量增加，永久覆盖在琴平，但没有发现在库特诺的关系，那里有更多的永久覆盖和较小的字段大小。3.小面积耕地的平均虫量高于大面积耕地。然而，在小型和大型耕地永久覆盖附近的昆虫数量没有差异。4.鹧鸪在小耕地的平均育雏大小增加永久覆盖在琴平，但不是在库特诺。没有发现差异，在平均育雏大小之间的小型和大型耕地。5.简化农业景观结构可能是农业集约化的一个重要特征，这导致了较低的肉鸡存活率。
1. The relationships between the agricultural landscape structure, as a function of arable field size and the occurrence of permanent cover, and the abundance of insect food and partridge chick survival were studied in two areas of Poland. One area had small and large fields (Czempin) and the other had only small fields (Kutno). Brood size was used as an index of chick survival and the number of plant bugs (Heteroptera) as an index of chick food resources. 2. The number of plant bugs in cereals increased with permanent cover in Czempin, but no relationship was found in Kutno where there was more permanent cover and smaller field sizes. 3. The average number of plant bugs was higher in small arable fields than in large fields. However, the number of insects near permanent cover in small and large arable fields did not differ. 4. The mean brood size of partridges in small arable fields increased with permanent cover in Czempin, but not in Kutno. No differences were found in mean brood size between small and large arable fields. 5. Simplifying the agricultural landscape structure could be an important feature of agricultural intensification that results in lower partridge chick survival.
